napari_prism.pp.zscore(adata, layer=None, copy=True)#

Apply z-score transformation along the rows of a given layer or .X. Each cell’s expression across vars will be scored -1 to 1.

i.e. A relative ‘rank’ of vars within each cell.

Parameters:

  • adata (AnnData) – Anndata object.

  • layer (Optional[str] (default: None)) – Expression layer to apply z-score transformation. If None, X is transformed.

  • copy (bool (default: True)) – Return a copy instead of writing inplace.

Return type:

AnnData | None

Returns:

AnnData object with row-wise z-score transformation applied. If copy is False, modifies the AnnData object in place and returns None.
