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.

Too high QUAL scores in Haplotypecaller gvcf
I'm getting some too-high QUAL scores in my VCF, the whole file is full of weird scores in the tens of thousands:
