Simple search
Search for an orthologous group. A group might be retrieved by its numerical identifier, a phylogenetic pattern or a gene. More advanced queries are possible.
Expansions/Deletions search
Search for orthologous group with duplications/deletions in a given species. The groups can be filtered for expansions with exactly one copy of the gene in all other species, or specific duplications with no copy of the gene in any of the other species, or groups with deletions in the given species with exactly one gene copy present in all other species.
