Hello everybody? I want to retrieve the ortholog sequences of only one representative of each taxonomy rank (for expample phylum). For example: I have 338 orthologs of the Entry ASPTN10103 (Q0CIE2). I want to download only one (or two or three) representative of any different Phylum. Any one knows if this can be done? and how?

Kind regards, Thank you,

Alejandro

You can use the REST API (https://omabrowser.org/api/docs), or if you are using R you could use our bioconductor package OmaDb (https://bioconductor.org/packages/release/bioc/html/OmaDB.html).

Either way, you could retrieve the taxonomy tree of all species in OMA (e.g. GET /api/taxonomy/?type=newick), retrieve the list of orthologs for your entry (GET /api/protein/ASPTN10103/orthologs/) and keep at most 1, 2 or 3 orthologs per phylum.
