Tutorial: Visualise pairwise genome alignments between WBPS genomes

posted 11 months ago by Dionysis Grigoriadis

From release 18 (WBPS18), users can browse and visualise whole genome alignments between genomes in the same taxonomic group. Cactus, a next-generation aligner that stores whole-genome alignments in a graph structure, was utilised to calculate multiple pairwise genome alignments between WBPS genomes. These genomes have been assigned to 5 big taxonomic groups, and pairwise alignments [read more]

About archive sites
