Bactopia Tool - `merlin`¶

MinmER assisted species-specific bactopia tool seLectIoN, or Merlin, uses distances based on the RefSeq sketch downloaded by bactopia datasets to automatically run species-specific tools.

Currently Merlin knows 16 spells for which cover the following:

Genus/Species	Tools
Escherichia / Shigella	ECTyper, ShigaTyper, ShigEiFinder
Haemophilus	hicap, HpsuisSero
Klebsiella	Kleborate
Legionella	legsta
Listeria	LisSero
Mycobacterium	TBProfiler
Neisseria	meningotype, ngmaster
Pseudomonas	pasty
Salmonella	SeqSero2, SISTR
Staphylococcus	AgrVATE, spaTyper, staphopia-sccmec
Streptococcus	emmtyper, pbptyper, SsuisSero

Merlin is avialable as an independent Bactopia Tool, or in the Bactopia with the --ask_merlin parameter. Even better, if you want to force Merlin to execute all species-specific tools (no matter the distance), you can use --full_merlin. Then all the spells will be unleashed!

Example Usage¶

bactopia --wf merlin \
  --bactopia /path/to/your/bactopia/results \ 
  --include includes.txt
