We’re moving the GATK website, docs and forum to a new platform. Read the full story and breakdown of key changes on this blog.
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.
We will be out of the office for a Broad Institute event from Dec 10th to Dec 11th 2019. We will be back to monitor the GATK forum on Dec 12th 2019. In the meantime we encourage you to help out other community members with their queries.
Thank you for your patience!
importance of known sites/resources
I have a general question about the importance of known VCFs (for BQSR and HC) and resources file (for VQSR). I am working on rice for which the only known sites are the dbSNP VCF files which are built on a genomic version older than the reference genomic fasta file which I am using as basis.
How does it affect the quality/accuracy of variants? How important is to have the exact same build of the genome as the one on which the known VCF is based? Is it better to leave out the known sites for some of the steps than to use the version which is built on a different version of the genome for the same species? In other words, which steps (BQSR, HC, VQSR etc) can be performed without the known sites/resource file?
If the answers to the above questions are too detailed, can you please point me to any document, if available, which might address this issue?
