The $SHELL
variable $ELOG_PATH
should be defined:
export ELOG_PATH=/your/favorite/elog/path
Also a useful $SHELL
variable is $BUILD_HOME
which should be the directory at the start of your working directory.
Checkout the sw_utils
repository by executing:
cd $BUILD_HOME
git clone https://github.com/cms-gem-daq-project/sw_utils.git
Then execute:
source sw_utils/scripts/setup_gemdaq.sh -c <cmsgemos tag> -g <gem-plotting tag> -G <gem-plotting dev version optional>
Tags for each of the repo's can be found:
-c X.Y.Z
)-g X.Y.Z -G A
)Where X
, Y
, Z
, and A
are integers, and most likely will be different for each of the repositories. If a development version is not to be used (normal case), you can drop the -G
option. If this is the first time you are executing the above command, it will create a Python virtualenv
for you and install the cmsgemos
and gemplotting
packages. It may take some time to download them, so be patient and do not interrupt the installation.
Example
source setup_gemdaq.sh -c 0.3.1 -g 1.0.0 -G 5
This command will install the following packages:
- cmsgemos version 0.3.1 (
-c 0.3.1
)- gemplotting version 1.0.0-dev5 (
-g 1.0.0 -G 5
)
In addition to installing the dependencies, the script will try to guess $DATA_PATH
based on the machine you are using.
To disable the python env execute:
deactivate
To re-enable the python env, source the script again:
cd $BUILD_HOME
source sw_utils/scripts/setup_gemdaq.sh
Note that you should always source the setup script from the same directory.
At P5, gem-plotting-tools
is installed system-wide. Setting it up is as simple as:
source /nfshome0/gempro/bin/get_gem_env.sh
This command should be run every time you connect. You can put it in your .bashrc
or .bash_profile
so it's done automatically.
When the analysis software decides a channel should be masked it is because it falls under one of the categories defined in the MaskReason
class of anaInfo.py. Multiple reasons can be assigned to a channel for why it is masked, and the total maskReason
is a 5-bit binary number. Presently these reasons are:
Name | Bit | Reason |
---|---|---|
NotMasked |
(none set) | the channel is not masked. |
HotChannel |
0 | the channel was identified as an outlier using the MAD algorithm, see talks by B. Dorney or L. Moureaux. |
FitFailed |
1 | the s-curve fit of the channel failed. |
DeadChannel |
2 | the channel has a burned or disconnected input. |
HighNoise |
3 | the channel has an scurve sigma above the cut value. |
HighEffPed |
4 | the channel has an effective pedestal above the cut value. |
The scurve sigma is the sigma of the modified error function used to fit the s-curve measurements. It comes from the TF1
object used to fit scurves in ScanDataFitter::fit()
of fitScanData.py.
A channel's effective pedestal is the percent of time a channel's comparator fires when injected charge is zero. This is determined from an s-curve measurement via:
effPed = scurve_fit_func.Eval(0) / n_pulses
Where n_pulses
are the number of charge injections for a given DAC value performed by the calibration module.
The analysis software will record the maskReason
in decimal reprementation. So for example a channel having maskReason = 24
corresponds to 0b11000
which means the channel was assigned the HighEffPed
and HighNoise
maskReasons.
The following procedure is used, note these steps must be executed one after another, without LV power cycle or action to cause a reset of the VFAT settings (e.g. SCA reset):
Step | Tool v2b (v3) | VFAT Data | Input Config | Generates |
---|---|---|---|---|
1 | trimChamber.py (trimChamberV3.py) |
Tracking | VThreshold1 (CFG_THR_ARM_DAC) = 100 , ztrim=4 |
Initial channel configuration chConfig.txt and trimRange settings. |
2 | confChamber.py |
N/A | chConfig.txt , trimRange in memory |
Nothing |
3 | ultraThreshold.py |
Tracking | Nothing | Generates updated channel config chConfig_MasksUpdated.txt and initial VFAT settings storing VThreshold1 and trimRange in vfatConfig.txt . |
4 | confChamber.py |
N/A | chConfig_MasksUpdated.txt and vfatConfig.txt |
Nothing |
5 | ultraThreshold.py (sbitThreshScanParallel.py) |
Trigger | Nothing | Generates updated VFAT settings vfatConfig_Updated.txt with final VThreshold1 values. |
Please note that while DeadChannel
is given in maskReason
these channels are never masked such that they can be tracked overtime.
If a channel was masked at the time of acquisition of a test involving an s-curve measurement (e.g. trimChamber(V3).py
or ultraScurve.py
) then it will be assigned the FitFailed
reason since the original reason is not known without referencing a previous scan.
When analyzing the above s-curves taken by trimChamber(V3).py
The following command line arguments are available for specifying the cut values for assigning the DeadChannel
, HighNoise
, and HighEffPed
pedestal.
Name | Type | Description |
---|---|---|
--maxEffPedPercent |
float | Value from 0 to 1. Threshold for setting the HighEffPed mask reason, if channel effPed > maxEffPedPercent * nevts then HighEffPed is set. |
--highNoiseCut |
float | Threshold for setting the HighNoise maskReason , if channel scurve_sigma > highNoiseCut then HighNoise is set. |
--deadChanCutLow |
float | If channel deadChanCutLow < scurve_sigma < deadChanCutHigh then DeadChannel is set, see Slide 22 for the origin of the default values in fC. |
--deadChanCutHigh |
float | If channel deadChanCutHigh < scurve_sigma < deadChanCutHigh then DeadChannel is set, , see Slide 22 for the origin of the default values in fC. |
Many of the tools found in the macros/
directory require a listOfScanDates.txt
file. These come in either two or three column versions and the parseListOfScanDatesFile(...)
of anautilities.py is designed to parse either version and provide the tool with the correct information. This means that, baring other command line arguments, the two formats are relatively interchangeable.
This should be a tab
deliminited text file. The first line of this file should be a list of column headers formatted as:
ChamberName scandate
Subsequent lines of this file are the values that correspond to these column headings. The value of the ChamberName
column must correspond to the value of one entry in the chamber_config
dictionary found in mapping/chamberInfo.py
. The next column is for scandate
values. Please note the #
character is understood as a comment, lines starting with a #
will be skipped.
A complete example for a single detector is given as:
ChamberName scandate
GE11-VI-L-CERN-0001 2017.08.11.16.30
GE11-VI-L-CERN-0001 2017.08.14.20.54
GE11-VI-L-CERN-0001 2017.08.30.15.03
GE11-VI-L-CERN-0001 2017.08.30.21.39
GE11-VI-L-CERN-0001 2017.08.31.08.28
GE11-VI-L-CERN-0001 2017.08.31.15.46
GE11-VI-L-CERN-0001 2017.09.05.11.41
GE11-VI-L-CERN-0001 2017.09.12.14.24
GE11-VI-L-CERN-0001 2017.09.13.16.45
This should be a tab
deliminited text file. The first line of this file should be a list of column headers formatted as:
ChamberName scandate <Indep. Variable Name>
Subsequent lines of this file are the values that correspond to these column headings. The value of the ChamberName
column must correspond to the value of one entry in the chamber_config
dictionary found in mapping/chamberInfo.py. The Indep. Variable Name is the independent variable that --branchName
will be plotted against, if it is not numeric please use the --alphaLabels
command line option. Please note the #
character is understood as a comment, lines starting with a #
will be skipped.
A complete example for a single detector is given as:
ChamberName scandate VT_{1}
GE11-VI-L-CERN-0002 2017.09.04.20.12 10
GE11-VI-L-CERN-0002 2017.09.04.22.52 20
GE11-VI-L-CERN-0002 2017.09.05.01.33 30
GE11-VI-L-CERN-0002 2017.09.05.04.21 40
GE11-VI-L-CERN-0002 2017.09.05.07.11 50
Here the ChamberName
is always GE11-VI-L-CERN-0002
and --branchName
will be plotted against VT_{1}
which is the Indep. Variable Name. Note the axis of interest will be assigned the label, with subscripts in this case, of VT_{1}
.
A complete example for multiple detectors is given as:
ChamberName scandate Layer
GEMINIm27L1 2019.09.04.20.12 GEMINIm27L1
GEMINIm27L2 2019.09.04.22.52 GEMINIm27L2
GEMINIm28L1 2019.09.05.01.33 GEMINIm28L1
GEMINIm28L2 2019.09.05.04.21 GEMINIm28L2
GEMINIp02L1 2019.09.05.07.11 GEMINIp02L1
GEMINIp02L2 2019.09.05.07.11 GEMINIp02L2
Here the ChamberName
is different for each line and --branchName
will be plotted against Layer
. Note since the Indep. Variable Name is not numeric the command line option --alphaLabels
must be used.
To automatically generate a set of listOfScanDates.txt
files for all s-curve measurements for each of the chambers defined in chamber_config.values()
of chamberInfo.py execute:
plotTimeSeries.py --listOfScanDatesOnly --startDate=2017.01.01
For each detector defined in chamber_config.values()
the listOfScanDAtes.txt
file will be found at:
$DATA_PATH/<ChamberName>/scurve/
If you are interested in generating a set of listOfScanDates.txt
files for measurements other than scurves supply the --anaType
argument at the time of execution like:
plotTimeSeries.py --listOfScanDatesOnly --startDate=2017.01.01 --anaType=<type>
The list of supported anaType
's are from ana_config.keys()
of anaInfo.py. In this case the listOfScanDAtes.txt
file for each chamber will be found at:
$DATA_PATH/<ChamberName>/<anaType>/
Analysis is broken down into either analyzing data taken with the python ultra scan tools or with xdaq.
The following tools exist to help you to analyze scans taken with the ultra tools in the vfatqc-python-scripts repository:
ana_scans.py
,anaUltraLatency.py
,anaUltraScurve.py
, andanaUltraThreshold.py
.See extensive documentation written on the GEM DOC Twiki Page.
For some test stands where you have configured the input L1A to pass only through a specific point of a detector you can use the data taken by ultraLatency.py
to calculate the efficiency of the detector. To help you perform this analysis the plot_eff.py
tool has been created.
The following table shows the mandatory inputs that must be supplied to execute the script:
Name | Type | Description |
---|---|---|
--latSig |
int | Latency bin for which efficiency should be determined from. |
-i , --infilename |
string | physical filename of the input file to be passed to plot_eff.py . The format of this input file should follow the Three Column Format. |
-p , --print |
none | Prints a comma separated table of the plot's data to the terminal. The format of this table will be compatible with the genericPlotter executable of the CMS_GEM_Analysis_Framework. |
-v , --vfat |
int | Specify VFAT to use when calculating the efficiency. |
The following table shows the optional inputs that can be supplied when executing the script:
Name | Type | Description |
---|---|---|
--bkgSub |
none | Background subtraction is used to determine the efficiency instead of a single latency bin. May be used instead of the --latSig option. |
--vfatList |
Comma separated list of int's | List of VFATs to use when calculating the efficiency. May be used instead of the --vfat option. |
Note if the --bkgSub
option is used then you must first call anaUltraLatency.py
for each of the scandates given in the --infilename
.
The format of this input file should follow the Three Column Format.
To calculate the efficiency using VFATs 12 & 13 in latency bin 39 for a list of scandates defined in listOfScanDates.txt
call:
plot_eff.py --infilename=listOfScanDates.txt --vfatList=12,13 --latSig=39 --print
To calculate the efficiency using VFAT4 using background subtraction first call anaUltraLatency.py
on each of the scandates given in listOfScanDates.txt
and then call:
plot_eff.py --infilename=listOfScanDates.txt -v4 --bkgSub --print
The following tools exist to help you to analyze scans taken with xDAQ:
anaXDAQLatency.py
See documentation written on the GEM DOC Twiki Page.
There are two tools for helping you to make arbitrary plots from python scan data:
gemPlotter.py
gemTreeDrawWrapper.py
The first tool is for plotting from multiple different scandates. The second tool is for making a given plot from a list of scandates, for each scandate.
The gemPlotter.py
tool is for making plots of an observable stored in one of the TTree
objects produced by the (ana-) ultra scan scripts vs an arbitrary indepdent variable specified by the user. Here each data point is from a different scandate. This is useful if you run mulitple scans in which only a single parameter is changed (e.g. applied high voltage, or VThreshold1
) and you want to track the dependency on this parameter.
Each plot produced will be stored as an output *.png
file. Additionally an output TFile
will be produced which will contain each of the plots, stored as TGraph
objects, and canvases produced.
The following table shows the mandatory inputs that must be supplied to execute the script:
Name | Type | Description |
---|---|---|
--anaType |
string | Analysis type to be executed, see tree_names.keys() of anaInfo.py for possible inputs |
--branchName |
string | Name of TBranch where dependent variable is found, note that this TBranch should be found in the TTree that corresponds to the value given to the --anaType argument |
-i , --infilename |
string | physical filename of the input file to be passed to gemPlotter.py . See Three Column Format for details on the format and contents of this file. |
-v , --vfat |
int | Specify VFAT to plot |
Note for those anaType
values which have the substring Ana
in their names it is expected that the user has already run ana_scans.py
on the corresponding scandate
to produce the necessary input file for gemPlotter.py
.
The following table shows the optional inputs that can be supplied when executing the script:
Name | Type | Description |
---|---|---|
-a , --all |
none | When providing this flag data from all 24 VFATs will be plotted. Additionally a summary plot in the typical 3x8 grid will be created showing the results of all 24 VFATs. May be used instead of the --vfat option. |
--alphaLabels |
none | When providing this flag gemPlotter.py will interpret the Indep. Variable as a string and modify the output X axis accordingly |
--axisMax |
float | Maximum value for the axis depicting --branchName . |
--axisMin |
float | Minimum value for the axis depicting --branchName . |
-c , --channels |
none | When providing this flag the --strip option is interpreted as VFAT channel number instead of readout board (ROB) strip number. |
-s , --strip |
int | Specific ROB strip number to plot for --branchName . Note for ROB strip level --branchName values (e.g. trimDAC ) if this option is not provided the data point (error bar) will represent the mean (standard deviation) of --branchName from all strips. |
--make2D |
none | When providing this flag a 2D plot of ROB strip/vfat channel vs. independent variable will be plotted whose z-axis value is --branchName . |
-p , --print |
none | Prints a comma separated table of the plot's data to the terminal. The format of this table will be compatible with the genericPlotter executable of the CMS_GEM_Analysis_Framework. |

--skipBadFiles |
none | TFiles that fail to load, or where the TTree cannot be successfully loaded, will be skipped. |
--showStat |
none | Causes the statistics box to be drawn on created plots. Note only applicable when used with --make2D . |
--vfatList |
Comma separated list of int's | List of VFATs that should be plotted. May be used instead of the --vfat option. |
--ztrim |
int | The ztrim value that was used when running the scans listed in --infilename |
The format of this input file should follow the Three Column Format.
To automatically consider the last two weeks worth of s-curve scans, run the script specifying vt1bump
option like this:
plotTimeSeries.py --vt1bump=10
resulting plots will be stored under
$ELOG_PATH/timeSeriesPlots/<chamber name>/vt1bumpX/
To make a 1D plot for a given strip of a given VFAT execute:
gemPlotter.py --infilename=<inputfilename> --anaType=<anaType> --branchName=<TBranch Name> --vfat=<VFAT No.> --strip=<Strip No.>
For example, to plot trimDAC
vs. an Indep. Variable Name defined in listOfScanDates.txt
for VFAT 12, strip number 49 execute:
gemPlotter.py -ilistOfScanDates.txt --anaType=trimAna --branchName=trimDAC --vfat=12 --strip=49
Additional VFATs could be plotted by either:
--rootOpt=UPDATE
,--vfatList
argument instead of the --vfat
argument, or-a
argument to make all VFATs.To make a 1D plot for a given VFAT execute:
gemPlotter.py --infilename=<inputfilename> --anaType=<anaType> --branchName=<TBranch Name> --vfat=<VFAT No.>
For example, to plot trimRange
vs. an Indep. Variable Name defined in listOfScanDates.txt
for VFAT 12 execute:
gemPlotter.py -ilistOfScanDates.txt --anaType=trimAna --branchName=trimRange --vfat=12
Note if TBranch Name is a strip level observable the data points (y-error bars) in the produced plot will represent the mean (standard deviation) from all of the VFAT's channels.
Additional VFATs could be plotted by either:
--rootOpt=UPDATE
,--vfatList
argument instead of the --vfat
argument, or-a
argument to make all VFATs.To automatically extend this to all channels execute:
gemPlotterAllChannels.sh <InFile> <anaType> <branchName>
To make a 2D plot for a given VFAT execute:
gemPlotter.py --infilename=<inputfilename> --anaType=<anaType> --branchName=<TBranch Name> --vfat=<VFAT No.> --make2D
Here the output plot will be of the form "ROB Strip/VFAT Channel vs. Indep. Variable Name" with the z-axis storing the value of --branchName
.
For example to plot trimDAC
for "ROB Strip vs. Indep. Variable Name" wher
For example to make a 2D plot with the z-axis as trimDAC
and the Indep. Variable Name defined in listOfScanDates.txt
for VFAT 12 execute:
gemPlotter.py -ilistOfScanDates.txt --anaType=trimAna --branchName=trimDAC --vfat=12 --make2D
Additional VFATs could be plotted by either:
--rootOpt=UPDATE
,--vfatList
argument instead of the --vfat
argument, or-a
argument to make all VFATs.The gemTreeDrawWrapper.py
tool is for making a given 'Y vs. X' plot for each scandate of interest. Here Y and X are quantities stored in TBranches
of one of the TTree
objects procued by the (ana-) ultra scan scripts. This is designed to complement gemPlotter.py
and should speed up plotting in general. This tool is essesntially a wrapper for the TTree::Draw()
method. To make full use of this tool you should familiarize yourself with the TTree::Draw()
documentation.
Additionally gemTreeDrawWrapper.py
can also fit produced plots with a function defined at runtime through the command line arguments.
Each plot produced will be stored as an output *.png
file. Additionally an output TFile
will be produced which will contain each of the plots, stored as TGraph
objects, canvases, and fits produced.
The following table shows the mandatory inputs that must be supplied to execute the script:
Name | Type | Description |
---|---|---|
--anaType |
string | Analysis type to be executed, see tree_names.keys() of anaInfo.py for possible inputs |
-i , --infilename |
string | physical filename of the input file to be passed to gemTreeDrawWrapper.py . See Two Column Format for details on the format and contents of this file. |
--treeExpress |
string | Expression to be drawn, corresponds to the varexp argument of TTree::Draw(). |
Note for those anaType
values which have the substring Ana
in their names it is expected that the user has already run ana_scans.py
on the corresponding scandate
to produce the necessary input file for gemTreeDrawWrapper.py
.
The following table shows the optional inputs that can be supplied when executing the script:
Name | Type | Description |
---|---|---|
--axisMaxX |

The format of this input file should follow the Two Column Format.
For example to make a plot from a latency scan, Nhits
vs. lat
for VFAT12, use the following example:
gemTreeDrawWrapper.py -ilistOfScanDates_TreeDraw.txt --anaType=latency --summary --treeExpress="Nhits:lat" --treeDrawOpt=APE1 --treeSel="vfatN==12" --axisMaxY=1000 --axisMinX=39 --axisMaxX=49 --drawLeg
This will produce one Nhits
vs. lat
plot for VFAT12 for each (ChamberName,scandate) pair found in listOfScanDates_TreeDraw.txt
. Additionally it will make one summary plot with a legend drawn which contains all of the produced plots.
For example to plot and fit an scurve from an scurve scan, Nhits
vs vcal
, for VFAT12 channel 45, use the following example:
gemTreeDrawWrapper.py -ilistOfScanDates_TreeDraw.txt --anaType=scurve --treeExpress="Nhits:vcal" --treeDrawOpt=APE1 --treeSel="vfatN==12 && vfatCH==45" --fitFunc="500*TMath::Erf((TMath::Max([2],x)-[0])/(TMath::Sqrt(2)*[1]))+500" --fitRange=70,150 --fitOpt="RM" --fitGuess=110,10,10
Here the fit that will be applied will be equivalent too:
myFunc = r.TF1(strName,"500*TMath::Erf((TMath::Max([2],x)-[0])/(TMath::Sqrt(2)*[1]))+500",70,150)
myFunc.SetParameter(0,110)
myFunc.SetParameter(0,10)
myFunc.SetParameter(0,10)
The fit option that will be used will be RM
. This fit will be applied to the scurve generated from VFAT12 channel 45 for each (ChamberName,scandate) pair found in listOfScanDates_TreeDraw.txt
.
The following tools exist for helping to understand scurve data:
gemSCurveAnaToolkit.py
plot_noise_vs_trim.py
plot_vfat_and_channel_Scurve.py
plot_vfat_summary.py
summary_plots.py
These tools can all by found in the macros/
subdirectory and are designed to be run on TFile
objects containing the scurveFitTree
TTree
object (e.g. produced by anaUltraScurve.py
). The first tool gemSCurveAnaToolkit.py
is for plotting the same (vfat,channel/ROBstr) scurve from a list of scandates and it is described in a dedicated subsection below. The rest of the tools above are for making plots from a single input file; the plots made by tools 2-4 are:
plot_noise_vs_trim.py
: Plots a channel/strip's scurve width (e.g. noise
) vs. trimDAC as a TH2D
on a TCanvas
, plot_vfat_and_channel_Scurve.py
: Plots a channel/strip's scurve as a TH1D
and its TF1
on a TCanvas
, andplot_vfat_summary.py
: Plots all scurves from a given VFAT as a TH2D
on a TCanvas
.Tool 5 summary_plots.py
produces the following plots from a single input file for a given VFAT depending on the command line argument supplied:
TH1D
,TH1D
,TH1D
,TH1D
,TH2D
, andTH2D
.The command line options for tools 2-5 are:
Name | Type | Description |
---|---|---|
-c , --channels |
none | Make plots vs VFAT channels instead of ROB strips. |
-i , --infilename |
string | Physical filename of the input file. Note this must be a TFile which contains the scurveFitTree TTree object. |
-s , --strip |
int | If the -c option is (not) supplied this will be the VFAT channel (ROB strip) the plot will be made for. |
-v , --vfat |
int | The VFAT to plot. |
Additionally tool 5 summary_plots.py
has the following additional command line options:
Name | Type | Description |
---|---|---|
-a , --all |
none | Equivalent to supplying -f and -x options. |
-f , --fit |
none | Make fit parameter plots. |
-x , --chi2 |
none | Make Chi2 plots. |
Note that for tool 5 summary_plots.py
you must supply at least one of these additional options {-a
,-f
,-x
}.
The gemSCurveAnaToolkit.py
tool is for plotting scurves and their fits from a given (vfat, vfatCH/ROBstr) from a list of scandates that correspond to TFile
objects which contain the scurveFitTree
TTree
(e.g. files produced by anaUltraScurve.py
). Each plot produced will be stored as an output *.png
file. Additionally an output TFile
will be produced which will contain each of the scurves and their fits.
Name | Type | Description |
---|---|---|
-c , --channels |
none | Make plots vs VFAT channels instead of ROB strips. |
-i , --infilename |
string | Physical filename of the input file to be passed to gemSCurveAnaToolkit.py . The format of this input file should follow the Two Column Format. |

To plot the scurves, and their fits, for VFAT0 channel 29 from a set of scandates defined in listOfScanDates_Scurve.txt
taken by ultraScurve.py
and analyzed with anaUltraScurve.py
you would call:
gemSCurveAnaToolkit.py -ilistOfScanDates_Scurve.txt -v0 -s29 --anaType=scurveAna -c --summary --drawLeg
This will produce a *.png
file for each of the scandates defined in listOfScanDates_Scurve.txt
and one *.png
file showing all the scurves with their fits drawn on it as a summary. Additionally an output TFile
will be produced containing each of the scurves and their fits.
While gemTreeDrawWrapper.py
and gemPlotter.py
allow you to plot observables from multiple runs sometimes you are interested in seeing the results made from anaUltraScurve.py
, from multiple scandates, on the same set of TCanvas
es. The tool plotSCurveFitResults.py
allows you to do this. The tool will create five output *.png
files and one TFile
which stores relevant plots for each VFAT from each of the input scandates. These five *.png
files are:
scurveFitSummaryGridAllScandates.png
, shows the fitSummary
curves from all input scandates on one TCanvas
in a 3-by-8 grid,scurveMeanGridAllScandates.png
, shows the distribution of s-curve mean positions from each VFAT from all input scandates on one TCanvas
in a 3-by-8 grid,scurveSigmaGridAllScandates.png
, as scurveMeanGridAllScandates.png
but for s-curve sigma,canvSCurveSigmaDetSumAllScandates.png
, shows a summary distribution of s-curve sigma positions from all VFATs of the detector from all scandates on one TCanvas
, andcanvSCurveMeanDetSumAllScandates.png
, as canvSCurveSigmaDetSumAllScandates.png
but for s-curve mean.The files will be found in $ELOG_PATH
along with the output TFile
, named scurveFitResultPlots.root
.
Name | Type | Description |
---|---|---|
-i , --infilename |
string | Physical filename of the input file to be passed to plotSCurveFitResults.py . The format of this input file should follow the Three Column Format. |
--alphaLabels |
none | When providing this flag plotSCurveFitResults.py will interpret the Indep. Variable as a string. |
--anaType |
string | Analysis type to be executed, taken from the list {'scurveAna','trimAna'}. |
--drawLeg |
none | Draws a TLegend on the output plots. For those 3x8 grid plots the legend will only be drawn on the plot for VFAT0. |
--rootName |
string | Name of output TFile . This file will be found in $ELOG_PATH . |
--rootOpt |
string | Option for creating the output TFile , e.g. {RECREATE ,UPDATE } |
--ztrim |
int | The ztrim value that was used when running the scans listed in --infilename |
The format of this input file should follow the Three Column Format. Note that here the Indep. Variable for each row will be used as the TLegend
entry if the --drawLeg
argument is supplied.
To plot results from a set of scandates defined in listOfScanDates_Scurve.txt
taken by either ultraScurve.py
or trimChamber.py
and analyzed with anaUltraScurve.py
you would call:
plotSCurveFitResults.py --anaType=scurveAna --drawLeg -i listOfScanDates_Scurve.txt --alphaLabels
This will produce the five *.png
files mentioned above along with the output TFile
.
timeHistoryAnalyzer.py
is a tool that finds when a channel turns bad (see below for the available definitions), and possibly when it is recovered. It takes as input a set of files produced by plotTimeSeries.py
, and the results are printed to the terminal.
The analysis proceeds in three steps, executed in the following order:
Scans that pass any the following cuts are removed:
--minScanAvgNoise
). This cuts scans with no or very few channels responding.--maxScanMaskedFrac
). This cuts e.g scans that produced no data and for which all fits failed.Note that the options are named in the positive way, ie they tell which scans to keep.
The time evolution of each channel is searched for successive scans with consistent behavior. A set of such scans "bad" scans for a given channel is called a (time) range; the definition of bad is user defined (see below).
Range finding starts with a list of scans, where each scan is marked as "good" or "bad". The definition of "bad" depends on what's being searched for (and "good" is always defined as "not bad"). The start of a range is determined by:
Then the range continues and the end of the range is determined by 5 consecutive good scans appearing (option: --numEndScans
). To prevent the printing of spurious ranges due to transient effects ranges with less than 4 "bad" scans in total are suppressed (option: --minBadScans
). A "range" found by this algorithm can have include some "good" scans.
As a side-effect, channels with sparse "bad" behavior are also extracted. This can be controlled by tightening the cuts in the algorithm above.
Three definitions of "bad" are currently available:
mask
: the channel under consideration is maskedmaskReason
: the channel under consideration has a non-zero maskReason
zeroInputCap
: the channel under consideration has an scurve width that is consistent with zero input capacitance (4.14E-02 < scurevWidth < 1.09E-01 fC
). The precise values can be controlled using the --minNoise
and --maxNoise
options.For every "range" found in each of the VFATs, the following properties are computed and printed in a table:
Column header | Meaning |
---|---|
ROBstr or vfatCH |
Strip number and VFAT channel, respectively |
Last known good | Date and time of the last good scan before the range ("never" if the range starts at the first scan) |
Range begins | Start date and time |
Range ends | End date and time ("never" if the range includes the lastest scan) |
#scans | Total number of scans (good and bad) |
masked% | Percentage of #scans where the channel is "masked" not to be confused with "bad (useful to investigate channels that behave badly once in a while) |
Initial maskReason |
maskReason for the first scan in the range |
Other subsequent maskReason s |
maskReason not present for the first scan but found in a later scan in the same range |
A summary table of initial maskReason
vs VFAT is also printed at the end.
Name | Type | Description |
---|---|---|
-i , --inputDir |
path | Input directory (=output directory of plotTimeSeries.py ) |
--ranges |
string | Defines the range selection algorithm. Allowed values: mask , maskReason , zeroInputCap |
--onlyCurrent |
none | Only show ranges that extend until the last scan |
Name | Type | Description |
---|---|---|
--minScanAvgNoise |
float | Minimum noise in fC, averaged over the whole detector, for a scan to be considered |
--maxScanMaskedFrac |
float | Maximum fraction of masked channel, over the whole detector, for a scan to be considered |
Name | Type | Description |
---|---|---|
--numEndScans |
int | Number of 'good' scans to end a range |
--minBadScans |
int | Minimum number of 'bad' scans to keep a range |
--minNoise |
float | Lower bound on noise for the zeroInputCap range finder, in fC |
--maxNoise |
float | Upper bound on noise for the zeroInputCap range finder, in fC |
The examples below assume that you have analyzed S-curves using plotTimeSeries.py, and that the output is located at:
$ELOG_PATH/timeSeriesPlots/<chamber name>/vt1bumpX/
Note that the above structure is created automatically by plotTimeSeries.py
.
The simplest possible call to timeHistoryAnalyzer.py
is:
timeHistoryAnalyzer.py -i $ELOG_PATH/timeSeriesPlots/<chamber name>/vt1bumpX/
This will use the default range finder, maskReason
, and settings. Depending on the detector and number of scans being analyzed, it may result in a lot of output being printed to the terminal. For every VFAT, you will get a table that looks like this:
ROBstr |
Last known good | Range begins | Range ends | #scans | Masked% | Initial maskReason |
Other subsequent maskReason s |
---|---|---|---|---|---|---|---|
18 | 2017.10.11.11.24 | 2017.10.13.12.53 | never | 127 | 100 | HotChannel,FitFailed | |
31 | 2017.10.11.11.24 | 2017.10.13.12.53 | never | 127 | 0 | DeadChannel | |
91 | 2017.06.15.15.10 | 2017.06.16.14.35 | 2018.02.06.12.07 | 107 | 47 | HotChannel | HighNoise |
93 | 2017.03.27.16.22 | 2017.03.29.13.27 | 2017.05.31.14.48 | 46 | 56 | HotChannel | |
93 | 2017.06.15.15.10 | 2017.06.16.14.35 | 2018.02.06.12.07 | 107 | 50 | HotChannel | HighNoise |
The meaning of the column headers is explained above. Here's the information that we can extract from the table (take a look here first if you're not confident with the meaning of maskReason
):
The example above used the maskReason
range finder. Let's try with zeroInputCap
:
timeHistoryAnalyzer.py -i $ELOG_PATH/timeSeriesPlots/<chamber name>/vt1bumpX/ --ranges zeroInputCap
Note that --ranges zeroInputCap
typically produces in a lot less output than the default.
At the end of its output, timeHistoryAnalyzer.py
prints the following table (some lines were stripped for concision):
HotChannel | FitFailed | DeadChannel | HighNoise | HighEffPed | |
---|---|---|---|---|---|
0 | 0 | 0 | 2 | 0 | 0 |
7 | 2 | 0 | 3 | 0 | 0 |
The first column is the VFAT number; the others correspond to the possible entries in maskReason
.
The table counts how many times a given MaskReason
appears in the "Initial maskReason
" column of each per-VFAT tables. Indeed, if we look at VFAT 0 for the above example, we find:
ROBstr |
Last known good | Range begins | Range ends | #scans | Masked% | Initial maskReason |
Other subsequent maskReason s |
---|---|---|---|---|---|---|---|
63 | 2017.04.07.15.46 | 2017.04.09.14.27 | never | 220 | 6 | DeadChannel | HotChannel |
64 | never | 2017.03.27.13.51 | never | 229 | 0 | DeadChannel |
The two entries in the DeadChannel column correspond to two ranges, that turn out to be from different strips (this may not be the case). Now VFAT 7:
ROBstr |
Last known good | Range begins | Range ends | #scans | Masked% | Initial maskReason |
Other subsequent maskReason s |
---|---|---|---|---|---|---|---|
0 | 2017.05.10.20.41 | 2017.05.31.09.21 | never | 182 | 0 | DeadChannel | |
2 | 2017.05.08.09.10 | 2017.05.10.19.57 | never | 184 | 1 | HotChannel,DeadChannel | |
3 | 2017.05.08.09.10 | 2017.05.10.19.57 | never | 184 | 1 | HotChannel,DeadChannel |
We can see that the three entries in the DeadChannel column and the two in the HotChannel column come from the same ranges.
Note When using the --onlyCurrent
option, there's only one range per channel, which makes the table easier to understand.
You may occasionally need to update the travis CI
docker which checks the code quality or you may want to transfer a number of files corresponding to a series of scandates from the P5 machine to another area. The packageFiles4Docker.py
tool enables you to do this. The output of packageFiles4Docker.py
will be a *.tar
file that:
$DATA_PATH
, and listOfScandates.txt
files supplied at runtime, and chamberInfo.py
file which can be placed in the docker for testing.Name | Type | Description |
---|---|---|
--fileListLat |
string | Specify Input Filename for list of scandates for latency files. |
--fileListScurve |
string | Specify Input Filename for list of scandates for scurve files. |
--fileListThresh |
string | Specify Input Filename for list of scandates for threshold files. |
--fileListTrim |
string | Specify Input Filename for list of scandates for trim files. |
--ignoreFailedReads |
none | Ignores failed read errors in tarball creation, useful for ignoring scans that did not finish successfully. |
--onlyRawData |
none | Files produced by anaUltra*.py scripts will not be included. |
--tarBallName |
string | Specify the name of the output tarball. |
--ztrim |
int | The ztrim value of interest for scandates given in --fileListTrim . |
-d , --debug |
none | prints the tarball command but does not make one. |
Please note that multiple --fileListX
arguments can be supplied at runtime, but at least one must be supplied.
Each of the --fileListX
arguments can be supplied with a listOfScanDates.txt
file that follows either the Two Column Format or the Three Column Format.
To make a tarball
of containing scurve scandates defined in listOfScanDates.txt
for GEMINIm01L1
execute:
packageFiles4Docker.py --ignoreFailedReads --fileListScurve=$DATA_PATH/GEMINIm01L1/scurve/listOfScanDates.txt --tarBallName=GEMINIm01L1_scurves.tar --ztrim=4 --onlyRawData
In this case failed read errors in the tar
command will be ignored and only the raw data, e.g. SCurveData.root
files, will be stored in the tarball following the appropriate file structure.
It may be that eventually you will need to re-analyze a large portion of the calibration dataset. While this is expected to be rare it would be excessively time consuming to analyze the data by hand. This section details the tools that exist to assist you in this process. All tools below are designed to work with the lxplus batch submission system based on LSF. Please note CERN IT plans to eventually transition from LSF to HTCondor. When this occurs these tools will need to be migrated to the new system. Instructions for doing so are available here.
This tool will allow you to re-analyze the scurve data in a straight forward way without the time consuming process of launching it by hand.
The following table shows the mandatory inputs:
Name | Type | Description |
---|---|---|
--anaType |
string | Analysis type to be executed, from list {'scurve','trim'} |
--chamberName |
string | Name of detector to be analyzed, must be present in chamber_config.values() of mapping/chamberInfo.py. Either this option or --infilename must be supplied. |
-i , --infilename |
string | Physical filename of the input file to be passed to clusterAnaScurve.py . The format of this input file should follow the Two Column Format. Either this option or --chamberName must be supplied. |
-q , --queue |
string | queue to submit your jobs to. Suggested options are {8nm , 1nh } |
-t , --type |
string | Specify GEB/detector type, e.g. "long" or "short" |
While the following table shows the optional additional inputs:
Name | Type | Description |
---|---|---|
--calFile |
string | File specifying CAL_DAC/VCAL to fC equations per VFAT. If this is not provided the analysis will default to hardcoded conversion for VFAT2 |
-c , --channels |
none | Output plots will be made vs VFAT channel instead of ROB strip |
-d , --debug |
none | If provided all cluster files will be created for inspection, and job submission commands printed to terminal, but no jobs will be submitted to the cluster. Strongly recommended calling with this option before submitting a large number of jobs. |
--endDate | string | If --infilenameis not supplied this is the ending scandate, in YYYY.MM.DD formate, to be considered for job submission. Default is Noneso the default behavior will be whatever datetime.today()` evaluates to. |
||
--extChanMapping |
string | Physical filename of a custom, non-default, channel mapping file. If not provided the default slice test ROB strip to VFAT channel mapping will be used. |
-f , --fit |
none | Fit scurves and save fit information to output TFile |
-p , --panasonic |
none | Output plots will be made vs Panasonic pins instead of ROB strip |
--startDate | string | If --infilenameis not supplied this is the starting scandate, in YYYY.MM.DD formate, to be considered for job submission. Default is 2017.01.01` so the start of the slice test will be used. |
||
--zscore |
float | Z-Score for Outlier Identification in the MAD Algorithm. For details see talks by B. Dorney or L. Moureaux |
--ztrim |
float | Specify the p value of the trim in the quantity: scurve_mean - ztrim * scurve_sigma |
Finally clusterAnaScurve.py
can also be passed the cut values used in assigning a maskReason described at Providing Cuts for maskReason at Runtime.
Before you start due to space limitations on AFS
it is strongly recommended that your $DATA_PATH
variable on lxplus point to the work area rather than the user area, e.g.:
export DATA_PATH=/afs/cern.ch/work/<first-letter-of-your-username>/<your-user-name>/<somepath>
In your work area you can have up to 100GB of space. If this is your first time using lxplus
you may want to increase your storage quota by following instructions here.
Now connect to the P5 dqm
machine. Then after setting up the env execute if you are intereted in a chamber ChamberName execute:
cd $HOME
plotTimeSeries.py --listOfScanDatesOnly --startDate=2017.01.01
packageFiles4Docker.py --ignoreFailedReads --fileListScurve=/gemdata/<ChamberName>/scurve/listOfScanDates.txt --tarBallName=<ChamberName>_scurves.tar --ztrim=4 --onlyRawData
Then connect to lxplus
. Checkout the repository if you have not done so already. Then after setting up the env execute:
cd $DATA_PATH
scp <your-user-name>@cmsusr.cms:/nfshome0/<your-user-name>/<ChamberName>_scurves.tar .
tar -xf <ChamberName>_scurves.tar
mv gemdata/<ChamberName> .
clusterAnaScurve.py -i <ChamberName>/scurve/listOfScanDates.txt --anaType=scurve -f -q 1nh
It may take some time to finish the job submission. Please pay attention to the output at the end of the clusterAnaScurve.py
command as it provodes helpful information for managing jobs and undersanding what comes next. Once your jobs are complete you should check that they all finished successfully. One way to do this is to check if any of them exited with status Exited
and check for the exit code. To do this execute:
grep -R "exit code" <ChamberName>/scurve/*/stdout/jobOut.txt --color
This will print a single line from all files where the string exit code
appears. For example:
% grep -R "exit code" GEMINIm01L1/scurve/*/stdout/jobOut.txt --color
GEMINIm01L1/scurve/2017.04.10.20.33/stdout/jobOut.txt:Exited with exit code 255.
GEMINIm01L1/scurve/2017.04.26.12.25/stdout/jobOut.txt:Exited with exit code 255.
GEMINIm01L1/scurve/2017.04.27.13.27/stdout/jobOut.txt:Exited with exit code 255.
GEMINIm01L1/scurve/2017.06.07.12.17/stdout/jobOut.txt:Exited with exit code 255.
GEMINIm01L1/scurve/2017.07.18.11.09/stdout/jobOut.txt:Exited with exit code 255.
GEMINIm01L1/scurve/2017.07.18.18.34/stdout/jobOut.txt:Exited with exit code 255.
For those lines that appear in the grep
output command you will need to check the standard err of the job which can be found in:
<ChamberName>/scurve/<scandate>/stderr/jobErr.txt
Note since some scans at P5 may have failed to complete successfully some jobs may intrinsically fail and be non-recoverable. If you have questions about a particular job you can try to search in the e-log around the scandate in time to see if anything occurred around this time that might cause problems for the scan. If you would like to re-analyze a failed job you can do so by calling:
source $DATA_PATH/<ChamberName>/scurve/<scandate>/clusterJob.sh
If a large number of jobs have failed you should spend some time trying to understand why, and then re-submit to the cluster, rather than attempting to analyze them all by hand.
Finally after you are satisfied that all the jobs that could complete successfully have completed you can:
For case 1, re-packaging the re-analyzed files into a tarball
, execute:
packageFiles4Docker.py --ignoreFailedReads --fileListScurve=<ChamberName>/scurve/listOfScanDates.txt --tarBallName=<ChamberName>_scurves_reanalyzed.tar --ztrim=4
mv <ChamberName>_scurves_reanalyzed.tar $HOME/public
chmod 755 $HOME/public/<ChamberName>_scurves_reanalyzed.tar
echo $HOME/public/<ChamberName>_scurves_reanalyzed.tar
Then provide the terminal output of this last command to one of the GEM DAQ Experts for mass-storage.
For case 2, create time series plots to summarize the entire dataset, execute:
<editor of your choice> $VIRTUAL_ENV/lib/python*/site-packages/gempython/gemplotting/mapping/chamberInfo.py
And ensure the only uncommented entries of the chamber_config
dictionary match the set of ChamberName
's that you have submitted jobs for. Then execute:
plotTimeSeries.py --startDate=2017.01.01 --anaType=scurve
Please note the above command may take some time to process depending on the number of detectors worth of data you are trying to analyze. Then a series of output *.png
and *.root
files will be found at:
$ELOG_PATH/timeSeriesPlots/<ChamberName>/vt1bump0/
If you would prefer to analyze ChamberName
's one at a time, or to have an output *.png
file for each VFAT, you can produce time series plots individually by executing the gemPlotter.py
commands provided at the end of the clusterAnaScurve.py
output. This might be preferred as when analyzing a large period of time the 3-by-8 grid plots that plotTimeSeries.py
will produce for you may be hard to read. In either case gemPlotter.py
or plotTimeSeries.py
will produce a TFile
for you in which the plots at the per VFAT level are stored for you to later investigate.
If you encounter issues in this procedure please spend some time trying to figure out what wrong on your side first. If after studying the documentation and reviewing the commands you have exeuted you still do not understand the failure please ask on the Software
channel of the CMS GEM Ops
Mattermost team or submit an issue to the github page.
