get_relation_mapping

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

Get relations from identifiers in the source prefix to target prefix with the given relation. :rtype: Mapping[str, str]

Warning

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

Example usage: get homology between HGNC and MGI:

>>> import pyobo
>>> human_mapt_hgnc_id = '6893'
>>> mouse_mapt_mgi_id = '97180'
>>> hgnc_mgi_orthology_mapping = pyobo.get_relation_mapping('hgnc', 'ro:HOM0000017', 'mgi')
>>> assert mouse_mapt_mgi_id == hgnc_mgi_orthology_mapping[human_mapt_hgnc_id]
