sainsc.utils.celltype_signatures
================================

.. py:function:: sainsc.utils.celltype_signatures(adata, *, celltype_col = 'leiden', layer = None, dtype = np.float32)

   Calculate gene expression signatures per 'cell type'.

   :param adata:
   :type adata: anndata.AnnData
   :param celltype_col: Name of column in :py:attr:`anndata.AnnData.obs` containing cell-type
                        information.
   :type celltype_col: str, optional
   :param layer: Which :py:attr:`anndata.AnnData.layers` to use for aggregation. If `None`,
                 :py:attr:`anndata.AnnData.X` is used.
   :type layer: str, optional
   :param dytpe: Data type to use for the signatures.
   :type dytpe: numpy.typing.DTypeLike

   :returns: :py:class:`pandas.DataFrame` of gene expression aggregated per 'cell type'.
   :rtype: pandas.DataFrame
