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.
Dropping Samples from gVCF
We are currently working on a project, and we have found that some of our samples were contaminated after the gVCF merging phase. Is it possible to remove samples from a merged gVCF (likely using SelectVariants), or would we need to re-merge only the good gVCFs into a new merged gVCF? (Note that we're actually working with a double-merged gVCF file containing ~5,000 samples, so re-merging would be potentially costly).
