GATK and ExomeCNV

PandoraPandora ItalyMember ✭

Hi, I'm trying to use ExomeCNV to detect the CNV on 2 chromosomes (13 and 17 for BRCA1 and BRCA2).

I use the manual on https://secure.genome.ucla.edu/index.php/ExomeCNV_User_Guide and for first part (the GATK part) I use the code on the instruction with the only variant on reference genome (I use hg19.fasta, is it correct?).

My output is;

Is it correct?

Then i proceed with the second part but when I try to load output.coverage.sample_interval_summary I have an error, in particular:
"The line 1 doesn't have 15 elements".
Where am I wrong?
Thank you for the help :)

    Hi,

    Yes, your command looks fine and the output (no reads filtered is fine). However, did you mark duplicates? The reference you used must be fine as long as you aligned your reads to it. (I'm guessing it is also fine because you did not get an error :smiley:

    I suspect the issue you are having is with the next step, the R command.

    Hi again,

    You should look into using the GATK tools for CNV! Here is a start :smile:

    I think @Sheila means http://gatkforums.broadinstitute.org/gatk/categories/gatk-4-alpha (ReCapSeg is the old, pre-GATK version of the CNV tools).
