Hi again,
The above was run using CNVkit 0.9.1
I just updated to 0.9.4 and got the same error.
(virtualenv_python_2.7.5) [apandey@papr-expanded01 ]$ cnvkit.py segment MAOC00944-3-6.cnr -o MAOC00944-3-6.cns -t 1e5 -p 1

/researchers/ahwan.pandey/Tools/virtualenv_python_2.7.5/lib/python2.7/site-packages/scipy/signal/_arraytools.py:45: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.

OK I think I figured it. The cuprit was the value I was using for "-t". I removed it altogether and it works.
Doesn't work
cnvkit.py segment MAOC00944-3-6.cnr -o MAOC00944-3-6.cns -t 1e5 -p 1
Works
cnvkit.py segment MAOC00944-3-6.cnr -o MAOC00944-3-6.cns -p 1
I got the "-t 1e5" from:
https://github.com/etal/cnvkit-examples/issues/1
Another issue now, it looks like I can't access the help info, wanted to check what values are acceptable for "-t" and what the default is.

Sorry for the trouble, here's the segment
help text:
usage: cnvkit.py segment [-h] [-o FILENAME] [-d DATAFRAME]
[-m {cbs,flasso,haar,none,hmm,hmm-tumor,hmm-germline}]
[-t THRESHOLD] [--drop-low-coverage]
[--drop-outliers FACTOR] [--rscript-path PATH]
[-p [PROCESSES]] [-v FILENAME] [-i SAMPLE_ID]
[-n NORMAL_ID]
[--min-variant-depth MIN_VARIANT_DEPTH]

filename
positional arguments:
filename Bin-level log2 ratios (.cnr file), as produced by
'fix'.
optional arguments:
-h, --help show this help message and exit
-o FILENAME, --output FILENAME
Output table file name (CNR-like table of segments,
.cns).
-d DATAFRAME, --dataframe DATAFRAME
File name to save the raw R dataframe emitted by CBS
or Fused Lasso. (Useful for debugging.)
-m {cbs,flasso,haar,none,hmm,hmm-tumor,hmm-germline}, --method {cbs,flasso,haar,none,hmm,hmm-tumor,hmm-germline}
Segmentation method (CBS, fused lasso, haar wavelet,
HMM), or 'none' for chromosome arm-level averages as
segments. [Default: cbs]
-t THRESHOLD, --threshold THRESHOLD
Significance threshold (p-value or FDR, depending on
method) to accept breakpoints during segmentation. For
HMM methods, this is the smoothing window size.
--drop-low-coverage Drop very-low-coverage bins before segmentation to
avoid false-positive deletions in poor-quality tumor
samples.
--drop-outliers FACTOR
Drop outlier bins more than this many multiples of the
95th quantile away from the average within a rolling
window. Set to 0 for no outlier filtering. [Default:
10]
--rscript-path PATH Path to the Rscript excecutable to use for running R
code. Use this option to specify a non-default R
installation. [Default: Rscript]
-p [PROCESSES], --processes [PROCESSES]
Number of subprocesses to segment in parallel. Give 0
or a negative value to use the maximum number of
available CPUs. [Default: use 1 process]
To additionally segment SNP b-allele frequencies:
-v FILENAME, --vcf FILENAME
VCF file name containing variants for segmentation by
allele frequencies.
-i SAMPLE_ID, --sample-id SAMPLE_ID
Specify the name of the sample in the VCF (-v/--vcf)
to use for b-allele frequency extraction and as the
default plot title.
-n NORMAL_ID, --normal-id NORMAL_ID
Corresponding normal sample ID in the input VCF
(-v/--vcf). This sample is used to select only
germline SNVs to plot b-allele frequencies.
--min-variant-depth MIN_VARIANT_DEPTH
Minimum read depth for a SNV to be displayed in the
b-allele frequency plot. [Default: 20]
-z [ALT_FREQ], --zygosity-freq [ALT_FREQ]
Ignore VCF's genotypes (GT field) and instead infer
zygosity from allele frequencies. [Default if used
without a number: 0.25]
I think you want -t 1e-5
instead of -t 1e5
.
Hello,
I am getting this error while using the segment function
Any Ideas what is going on?
Thanks!
