msmu.utils.reindex_obs

Reindex the observation (.obs) of the MuData object to ensure consistency across modalities.

Parameters:

Name	Type	Description	Default
mdata	MuData	MuData with the requested column in both global .obs and every modality .obs.	required
column	str	Column whose string-converted values become observation names.	required

Returns:

Type	Description
MuData	A copied MuData with global and modality observation indices replaced. The old index is retained as a column by reset_index.

Notes

Missing columns raise KeyError. Use identifiers consistent across modalities; the input is unchanged.

Examples:

import msmu as mm
renamed = mm.utils.reindex_obs(mdata, column="sample")
