liana.resource.get_hcop_orthologs#

liana.resource.get_hcop_orthologs(target_organism='mouse', url=None, filename=None, min_evidence=3, columns=None)#

Download the HCOP orthology file and filter it by minimum evidence.

Parameters:

  • target_organism (str) – Target organism for orthology mapping. Default is "mouse". Supported values: anole_lizard, c.elegans, cat, cattle, chicken, chimpanzee, dog, fruitfly, horse, macaque, mouse, opossum, pig, platypus, rat, s.cerevisiae, s.pombe, xenopus, zebrafish. The target-organism column in the returned DataFrame follows the pattern {target_organism}_symbol (e.g. mouse_symbol, rat_symbol).

  • url (str, optional) – Override the download URL. If None (default), the URL is constructed from target_organism using the HGNC Google Cloud Storage bucket.

  • filename (str, optional) – Local filename to save the downloaded file. Derived from the URL if None.

  • min_evidence (int) – Minimum number of orthology resources that must support an interaction.

  • columns (list, optional) – Columns to keep in the final DataFrame. If None, all columns are kept.

Returns:

mapping

DataFrame with the HCOP mapping.

HCOP is a composite database combining data from various orthology resources. It provides a comprehensive set of human orthologs across many species.
