get_relation

pyobo.get_relation(prefix, source_identifier, relation, target_prefix, *, use_tqdm=False, force=False)[source]

Get the target identifier corresponding to the given relationship from the source prefix/identifier pair. :rtype: Optional[str]

Warning

Assumes there’s only one version of the property for each term.

Example usage: get homology between MAPT in HGNC and MGI:

>>> import pyobo
>>> human_mapt_hgnc_id = '6893'
>>> mouse_mapt_mgi_id = '97180'
>>> assert mouse_mapt_mgi_id == pyobo.get_relation('hgnc', human_mapt_hgnc_id, 'ro:HOM0000017', 'mgi')
