OMA (Orthologous MAtrix) is a database of orthologs extracted from available complete genomes.[1][2] The orthology predictions of OMA are available in several forms:
- OMA Pairs: for a given gene, a list of predicted orthologs in other species is provided.
- OMA Groups: a set of genes across different species which are all orthologous.
- OMA Hierarchical Groups: the set of all genes that have evolved from a single ancestral gene in a given taxonomic range.
- OMA Genome Pair view: the list of all predicted orthologs between two species.
