I tried running Strelka. First I run it on some data and it has worked , but when i run it again on the the same data et other ones , T got empty VCFs: There is a VCF header but no calls.
There is no error in the logs files so I can't find where is the problem.
I have uninstall and install Strelka tool again but I had always the same results: empty VCFs with only header and logs file without any error.
is there a reason for this?
Thank you for ur help.
