Use the following form to download the list of all predicted orthologs between a pair of genomes of interest. Since orthologs are sometimes 1:many or many:many relations, this download will return more orthologs than what is covered by the OMA groups. The result is returned as a tab-separated text file, each line corresponding to one orthologous relation. The columns are the two IDs, the type of orthology (1:1, 1:n, m:1 or m:n) and (if available) the OMA group containing both sequences.
