**What it does**

+ Computes VAFs in normal and tumor samples.
+ Uses AD field of genotypes (##FORMAT ID=AD), composed of REF and ALT Read depths, separated by a comma.
+ A new genotype field 'VAF" (##FORMAT IF=VAF) is generated
+ VAF = AD(ALT) / (AD(ALT) + AD(REF))

-------

**Inputs**

1. A somatic varscan VCF with AD field in third position.
2. The AD field must be composed of two integers separated by a comma.

-------

**Output**

+ A VCF file
+ A line '##FORMAT=&lt;ID=VAF,Number=R,Type=float,Description="Variant Allele Frequency"&gt;' is added in the header
+ The VAF value is added in both normal and tumor genotype column, as a last field
