Histogram not filled for latency scan(m_RunType = 2)

[JohnyJaramillo]

Brief summary of issue

Latency scans shows values in cero for all the OH in the cosmic stand.

Types of issue

• [X] Bug report (report an issue with the code)
• [ ] Feature request (request for change which adds functionality)

Expected Behavior

Current Behavior

*.raw files copied to NAS and located in:
/data/bigdisk/GEM-Data-Taking/GE11_QC8/Cosmics/run000456/

unpacker (ferol) and LightDQM executed using runLDQM.sh script:
runLDQM.sh -i 1 -r 456

Normal termination, output file:
/data/bigdisk/GEM-Data-Taking/GE11_QC8/Cosmics/run000456/run000456_allLumi_index000000.analyzed.root

Analysis script shows a bug:
[gemuser@gem904qc8daq ~]$ anaXDAQLatency.py -s 6 --scanmin 50 --scanmax 75 /data/bigdisk/GEM-Data-Taking/GE11_QC8/Cosmics/run000456/run000456_allLumi_index000000.analyzed.root
Traceback (most recent call last):

    if 'gemType' not in inFile.latTree.GetListOfBranches():
NameError: name 'inFile' is not defined
[gemuser@gem904qc8daq ~]$ 

Fix hardcoded in local copy:
cd /home/gemuser/fsimone
python anaXDAQLatency.py -s 6 --scanmin 50 --scanmax 75 /data/bigdisk/GEM-Data-Taking/GE11_QC8/Cosmics/run000456/run000456_allLumi_index000000.analyzed.root -r 456

Output plots are empty

Steps to Reproduce (for bugs)

1. run in QC8 machine:

   [gemuser@gem904qc8daq ~]$ anaXDAQLatency.py -s 6 --scanmin 50 --scanmax 75 /data/bigdisk/GEM-Data-Taking/GE11_QC8/Cosmics/run000456/run000456_allLumi_index000000.analyzed.root

this will be fixed in PR#291

The problem is in the unpacker version installed on gem904qc8daq which doesn't fll the relevant histograms for a latency scan (m_RunType = 2)

Since the main issue looks like a lack of update due to a lack of releasing (because of the workaround used to reduced memory consumption), shouldn't something be done for the legacy release? I also see many branches, some of them having already been merged.

Wouldn't it be good to create one release/legacy branch like in the other repositories as well as one branch per setup at CERN, based on that branch? @mexanick?

Yes, this makes sense. I have to think a bit on how to do that more accurately, eventually avoiding the extra branches. I will expand at tomorrow's dev meeting on this.
