PURPOSE Parsnp is a command-line-tool for efficient microbial core genome alignment and SNP detection. Parsnp was designed to work in tandem with Gingr, a flexible platform for visualizing genome alignments and phylogenetic trees; both Parsnp and Gingr form part of the Harvest suite. Parsnp is implemented in C++ and Python. COPYRIGHT LICENSE Copyright © 2014, Battelle National Biodefense Institute (BNBI); all rights reserved.
