**VarScan Overview**

VarScan_ performs variant detection for massively parallel sequencing data, such as exome, WGS, and transcriptome data.
It calls variants from a mpileup dataset and produces a VCF 4.1. Full documentation is available online_.

This tool calls germline/somatic variants from tumor-normal pileups.

.. _online: http://dkoboldt.github.io/varscan/using-varscan.html

**Input**

::

  mpileup file - The SAMtools mpileup files for the normal and tumor tissue
 

**Output**

VarScan produces a VCF 4.1 dataset as output.
