OMA Browser Datasets

OMA is a method and database for the inference of orthologs among complete genomes. We provide browsable orthology predictions, APIs, flat file downloads and a standalone version of the inference algorithm on our main website: https://omabrowser.org

This zenodo record contains flat files of archive and current releases of the OMA Browser.

The most important files are:
