sourmash

The sourmash module produces summary statistics from the sourmash tool. The module can summarise data from the following sourmash output files (descriptions from command line help output):

  • sourmash compare
    • create a similarity matrix comparing many samples.
  • sourmash gather
    • search a metagenome signature against databases.

Additional information on sourmash and its outputs is available on the sourmash documentation website.

sourmash gather is modelled after the Kraken module, and builds a bar graph that shows the coverage of top-5 genomes covered most by all samples. The number of top genomes can be customized in the config file:

sourmash:
gather:
top_n: 5
