Welcome to metaPhOrs

MetaPhOrs is a public repository of phylogeny-based orthologs and paralogs that were computed using phylogenetic trees available in twelve public repositories. Currently, over 6.8 billion of unique homologs are deposited in MetaPhOrs database. These predictions were retrieved from 7 million Maximum Likelihood trees for 2,714 species. For each prediction, MetaPhOrs provides a Consistency Score and Evidence Level describing its goodness, together with number of trees and links to their source databases.
