scglue.data.transfer_labels

scglue.data.transfer_labels(ref, query, field, n_neighbors=5, use_rep=None, key_added=None, **kwargs)

Transfer discrete labels from reference dataset to query dataset

Parameters

• ref (AnnData) – Reference dataset

• query (AnnData) – Query dataset

• field (str) – Field to be transferred in ref.obs (must be discrete)

• n_neighbors (int) – Number of nearest neighbors used for label transfer

• use_rep (Optional[str]) – Data representation based on which to find nearest neighbors, by default uses {ref, query}.X.

• key_added (Optional[str]) – New query.obs key added for the transfered labels, by default the same as field.

• **kwargs – Additional keyword arguments are passed to sklearn.neighbors.NearestNeighbors

Return type

None
