Best Practices for Variant Calling with the GATK

The presentations below were filmed during the March 2015 GATK Workshop, part of the BroadE Workshop series. At the time of this workshop, the current version of Broad’s Genome Analysis Toolkit (GATK) was version 3.3.

This workshop focused on the core steps involved in calling variants with Broad's Genome Analysis Toolkit, using the "Best Practices" developed by the GATK team. View the workshop materials below to gain an understanding of the rationale, theory, and real-life applications of GATK Best Practices. Learn why each step is essential to the calling process, what key operations are performed on the data at each step, and how to use the GATK tools to get the most accurate and reliable results out of your dataset. 

NOTE: The most up-to-date information can be accessed at the GATK website under Best Practices.
