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.
Pipelining GATK with WDL and Cromwell
We aim to provide the research community with a range of options for running our Best Practices workflows exactly the same way we do it in-house at the Broad Institute. To that end, we make all our workflow scripts available publicly in Github under a dedicated organization called gatk-workflows, and we provide Docker containers for all versions of GATK (since 2018) in DockerHub. See the Best Practices to browse the pipelines by use case.
GATK's preferred pipelining solution: WDL + Cromwell
Our workflows are written in WDL, a user-friendly scripting language maintained by the OpenWDL community. Cromwell is an open-source workflow execution engine that supports WDL as well as CWL, the Common Workflow Language, and can be run on a variety of different platforms, both local and cloud-based. We take advantage of Cromwell's flexibility in our own work: we do some of our initial development work on the Broad's UGER cluster, then we run at scale on Google Cloud. This allows us to run exactly the same scripts regardless of the compute environment.
