+**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 estimates the relative tumor copy number from tumor-normal pileups.

+
+**Input**
+
+::
+
+  mpileup file - The SAMtools mpileup files for the normal and tumor tissue
+ 
+
+**Output**
+
+VarScan produces a VCF 4.1 dataset as output.
