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

.. py:function:: sainsc.utils.celltype_signatures(adata, *, celltype_col = 'leiden', agg_method = 'mean')

   Calculate gene expression signatures per 'celltype'.

   Note, that this will make a dense copy of `adata.X` therefore potentially leading
   to large memory usage.

   :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 agg_method: Function to aggregate gene expression per cluster used by
                      :py:meth:`pandas.DataFrame.agg`.
   :type agg_method: str or collections.abc.Callable, optional

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