Convenience wrapper around tiledbsoma.Experiment query, to build and execute a query, and return it as an anndata.AnnData object.

Parameters:

• census – The census object, usually returned by open_soma().

• organism – The organism to query, usually one of "Homo sapiens or "Mus musculus".

• measurement_name – The measurement object to query. Defaults to "RNA".

• X_name – The X layer to query. Defaults to "raw".

• X_layers – Additional layers to add to anndata.AnnData.layers.

• obs_value_filter – Value filter for the obs metadata. Value is a filter query written in the SOMA value_filter syntax.

• obs_coords – Coordinates for the obs axis, which is indexed by the soma_joinid value. May be an int, a list of int, or a slice. The default, None, selects all.

• var_value_filter – Value filter for the var metadata. Value is a filter query written in the SOMA value_filter syntax.

• var_coords – Coordinates for the var axis, which is indexed by the soma_joinid value. May be an int, a list of int, or a slice. The default, None, selects all.

• obsm_layers – Additional obsm layers to read and return in the obsm slot.

• obsp_layers – Additional obsp layers to read and return in the obsp slot.

• varm_layers – Additional varm layers to read and return in the varm slot.

• varp_layers – Additional varp layers to read and return in the varp slot.

• obs_embeddings – Additional embeddings to be returned as part of the obsm slot. Use get_all_available_embeddings() to retrieve available embeddings for this Census version and organism.

• var_embeddings – Additional embeddings to be returned as part of the varm slot. Use get_all_available_embeddings() to retrieve available embeddings for this Census version and organism.

• obs_column_names – Columns to fetch for obs dataframe.

• var_column_names – Columns to fetch for var dataframe.

Returns:

An anndata.AnnData object containing the census slice.
