=====================================================================
Filter genes based on arbitrary attributes (`scanpy.pp.filter_genes`)
=====================================================================

Keep genes that have at least `min_counts` counts or are expressed in at
least `min_cells` cells or have at most `max_counts` counts or are expressed
in at most `max_cells` cells. Other gene attributes can be used for filtering
too if available.
