Workshop Description

This workshop uses materials developed by the Broad Institute to teach Variant Discovery with GATK.  Attendees with no prior experience in variant calling are recommended to review all of the materials below before coming to the workshop. This early preparation will allow a focus on the specific issues of running GATK on the UCLA hoffman2 cluster rather than introducing the GATK variant calling pipeline. There will also be a focus on post variant discovery quality control steps as time allows.
