RT Journal Article SR Electronic T1 Rapid Core-Genome Alignment and Visualization for Thousands of Intraspecific Microbial Genomes JF bioRxiv FD Cold Spring Harbor Laboratory SP 007351 DO 10.1101/007351 A1 Todd J. Treangen A1 Brian D. Ondov A1 Sergey Koren A1 Adam M. Phillippy YR 2014 UL http://biorxiv.org/content/early/2014/07/22/007351.abstract AB Though many microbial species or clades now have hundreds of sequenced genomes, existing whole-genome alignment methods do not efficiently handle comparisons on this scale. Here we present the Harvest suite of core-genome alignment and visualization tools for quickly analyzing thousands of intraspecific microbial strains. Harvest includes Parsnp, a fast core-genome multi-aligner, and Gingr, a dynamic visual platform. Combined they provide interactive core-genome alignments, variant calls, recombination detection, and phylogenetic trees. Using simulated and real data we demonstrate that our approach exhibits unrivaled speed while maintaining the accuracy of existing methods.
