NVIDIA Parabricks v4.4.0

somatic (Somatic Variant Caller)

Run a somatic variant workflow.

The somatic tool processes the tumor FASTQ files, and optionally normal FASTQ files and knownSites files, and generates tumor or tumor/normal analysis. The output is in VCF format.

Internally the somatic tool runs several other Parabricks tools, thereby simplifying your work flow.
