Introduction

OrthoFinder is a fast, accurate and comprehensive platform for comparative genomics. It finds orthogroups and orthologs, infers rooted gene trees for all orthogroups and identifies all of the gene duplication events in those gene trees. It also infers a rooted species tree for the species being analysed and maps the gene duplication events from the gene trees to branches in the species tree. OrthoFinder also provides comprehensive statistics for comparative genomic analyses. OrthoFinder is simple to use and all you need to run it is a set of protein sequence files (one per species) in FASTA format. 1

Installed version(s)

The following versions are installed and currently available...

... on environment hpc-env/8.3:

  • OrthoFinder/2.5.2-foss-2019b

Loading / Using OrthoFinder

To load the desired version of the module, use the module load command, e.g.

module load hpc-env/8.3
module load OrthoFinder

Always remember: this command is case sensitive!

To find out on how to use OrthoFinder, you can just type in orthofinder -h to print out a help text to get you started:

$ orthofinder -h
