liana.utils.get_variable_loadings(adata: AnnData | MuData, varm_key: str | None = None, view_sep: str | None = None, variable_sep: str | None = None, pair_sep: str | None = None, var_names: list = ['ligand_complex', 'receptor_complex'], pair_names: list = ['source', 'target'], drop_columns: bool = True)

Extract variable loadings from an AnnData object.

Parameters:

adata

Annotated data object.

varm_key: str

Key to use when extracting variable loadings from mdata.varm

view_sep: str

Separator to use when splitting view:variable names into view and variable

variable_sep: str

Separator to use when splitting variable names into var_names (‘ligand_complex’ and ‘receptor_complex’ by default)

pair_sep: str

Separator to use when splitting view names into pair_names (‘source’ and ‘target’ by default)

drop_columns: bool

If True, drop the view:variable column

Returns:

Returns a pandas DataFrame with the variable loadings for the specified index.
