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.
Does CombineVariants support the gvcf format ?
I am merging several genome vcf files apparently created by gvcftools . I noticed that CombineVariants is incorrectly summing allele counts (AC) in some corner cases, and was wondering if the format  was supported?
If the format should be supported by the CombineVariants tool (gvcf is VCF 4.1 conformant), I have isolated a minimal example that should be of help for bugfixing.
