If you happen to see a question you know the answer to, please do chime in and help your fellow community members. We encourage our fourm members to be more involved, jump in and help out your fellow researchers with their questions. GATK forum is a community forum and helping each other with using GATK tools and research is the cornerstone of our success as a genomics research community.We appreciate your help!
Test-drive the GATK tools and Best Practices pipelines on Terra
Check out this blog post to learn how you can get started with GATK and try out the pipelines in preconfigured workspaces (with a user-friendly interface!) without having to install anything.
[GATK 22.214.171.124] No non-zero singular values were found in creating a panel of normals for somatic CNV
I got an exception below in creating a PoN for somatic CNV on about 80 WGS samples. It consists of ~30 males and ~50 females. I was able to create PoNs successfully for each sex separately, but not all together. Sex chromosomes were excluded for the PoN creation for both sexes.
The exception message suggests to set
minimum-interval-median-percentile to a higher value. I wonder how higher it should be or what it means. Would you also help me understand the argument,
