**What it does**

::

 VarScan is a platform-independent mutation caller for targeted, exome, and whole-genome resequencing data generated on Illumina, SOLiD, Life/PGM, Roche/454, and similar instruments. The newest version, VarScan 2, is written in Java, so it runs on most  operating systems. It can be used to detect different types of variation:

    Germline variants (SNPs an dindels) in individual samples or pools of samples.
    Multi-sample variants (shared or private) in multi-sample datasets (with mpileup).
    Somatic mutations, LOH events, and germline variants in tumor-normal pairs.
    Somatic copy number alterations (CNAs) in tumor-normal exome data.


**Input**

::

  mpileup normal file - The SAMtools mpileup file for normal
  mpileup tumor file - The SAMtools mpileup file for tumor
 

**Parameters**

::

  min-coverage	
  	Minimum read depth at a position to make a call [8]

  min-coverage-normal	
  	Minimum coverage in normal to call somatic [8]
  	
  min-coverage-tumor	
  	Minimum coverage in tumor to call somatic [6]
  	
  min-var-freq 
  	Minimum variant frequency to call a heterozygote [0.10]  	  	

  min-freq-for-hom
  	Minimum frequency to call homozygote [0.75]
  	
  normal-purity 
  	Estimated purity (non-tumor content) of normal sample [1.00]
  	
  tumor-purity
  	Estimated purity (tumor content) of tumor sample [1.00]
  
  p-value
  	Default p-value threshold for calling variants [0.99]
  	
  somatic-p-value
  	P-value threshold to call a somatic site [0.05]  	
  
  strand-filter
  	If set to 1, removes variants with >90% strand bias
  	
  validation 
  	If set to 1, outputs all compared positions even if non-variant
  
  output-vcf
  	If set to 1, outputs in VCF format [Default]
