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.
downsampling coverage in UnifiedGenotyper
As I saw from this link :http://gatkforums.broadinstitute.org/discussion/1237/how-unified-genotyper-works-retired
downsampling selects some subset reads randomly in Unified Genotype, meanwhile random seed values are affected by several things like multithreading and intervals run in the thread.
I want to ask if there is a "tool" in GATK could select subset reads not randomly, I mean with some intentions.
