Variant calling workflow and Report page overview
Somatic variant calling starts with the BAM files produced by our Alignment/QC pipeline, variants are called using Mutect2 from GATK, and then annotated using snpEff. The report page provides an interactive table to browse and filter the raw variant calls and summary statistics are available as well.
