[ensembl-dev] REST API 'or' question

[Andy Yates]

Hi Matthias,

I've cc'd in the ensembl dev mailing list as hopefully my answer will help others with the same question. The REST homology endpoint allows you to specify more than one target taxon to provide the kind of query you want e.g.

http://beta.rest.ensembl.org/homology/id/ENSG00000157764.json?target_taxon=10090;target_taxon=cow;type=orthologues

This will return the orthologues of human BRAF in mouse and cow in JSON. You can add as many target_taxon attributes as you need. One disadvantage of the REST API is that it is not a batch download system. Should you want all orthologues of human to mouse & cow you would be better served by BioMart.

Hope this helps,

Andy

(I am interested in a set of 5 species). Of'course I can do seperate targeted queries or non-target restricted queries and filter them locally.
