I am using CONTRA for CNV detection. I have run it successfully once. However, I was trying to run CONTRA again last week, it keeps giving me these errors:

Does this seem a python issue? I have also downloaded python version 2.7, but I have got the same error messages.

Can anyone help me on this?

Thanks,

Hi Dan, thanks for the reply. I think that is an intermediate file generated by CONTRA. I thought it was because python could not run properly (look at the first several lines), thus this temp.txt file could not be generated...

Can you verify that this directory exists?

/mnt/gfsusr/files/data/test/seqdata/All_Cases/project_TD_QC_test1/test1_20150728/project_TD_QC_test1_TD/calls/contra/buf/testData/

Did you read the error trace carefully? Look at the last line. It's pretty clearly stating that it can't find the directory you pointed it to:

  File "/mnt/gfsusr/files/data/bin/CONTRA.v2.0.6/contra.py", line 583, in main
    t1 = int(file.readlines(open(folder+"temp.txt"))[0].strip("\n"))
IOError: [Errno 2] No such file or directory:'/mnt/gfsusr/files/data/test/seqdata/All_Cases/project_TD_QC_test1/test1_20150728/project_TD_QC_test1_TD/calls/contra/buf/testData/temp.txt'

Hi Dan, I have checked that. The path

'/mnt/gfsusr/files/data/test/seqdata/All_Cases/project_TD_QC_test1/test1_20150728/project_TD_QC_test1_TD/calls/contra/buf/testData'

is there, but the temp.txt file was not successfully generated by CONTRA. The whole 'contra/but/testData/' directory was all generated by CONTRA.

I'm a bit late replying, but the original error of this thread is caused by a missing part of bedtools: Contra cannot find: convertBam

Make sure to reinstall bedtools as described in the contra documentation and double check that all bedtools executables are available in your $PATH.
