toolset for short variant discovery in genetic sequence data

 vt is a variant tool set that discovers short variants from Next Generation
 Sequencing data.
 .
 Vt-normalize is a tool to normalize representation of genetic variants in
 the VCF. Variant normalization is formally defined as the consistent
 representation of genetic variants in an unambiguous and concise way. In
 vt a simple general algorithm to enforce this is implemented.
