Ion Torrent Variant Caller (TVC) is a genetic variant caller for Ion Torrent sequencing platforms, and is specially optimized to exploit the underlying flow signal information in the statistical model to evaluate variants. Torrent Variant Caller is designed to call single-nucleotide polymorphisms (SNPs), multi-nucleotide polymorphisms (MNPs), insertions, deletions, and block substitutions.

Usage
