Heads up:
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!

How to judge convergence on BQSR

A nice day to you! Someone said "When the plots of BQSR don't change dramatically, it is convergence." I generated a pdf file afer the command
java -Djava.io.tmpdir=/mnt/tmp -jar $GATKPATH/GenomeAnalysisTK.jar -T BaseRecalibrator -R $REF -BQSR first_round_recal_data.table -before second_round_recal_data.table -after third_round_recal_data.table -o output.pdf
And I got the output file. Could you tell if my dataset convergence? Which part do I need to focus on during judge (which parts should be compared)? Thanks for your generous helping :blush:
