snapatac2.concat#

snapatac2.concat(adatas, *, join='inner', label=None, keys=None, file=None, backend=None)#

Concatenates AnnData objects.

When file is provided, this function saves the merged AnnData object on disk in a streaming fashion. This is memory efficient and allows merging large datasets that do not fit into memory.

Parameters:

adatas (list[AnnData]) – List of AnnData objects to concatenate.
join (Literal['inner', 'outer']) – How to handle observations and variables that are not shared between all AnnData objects.
label (str | None) – Column in axis annotation (i.e. .obs or .var) to place batch information in. If it’s None, no column is added.
keys – Names for each object being added. These values are used for column values for label.
file (Path | None) – If provided, the concatenated AnnData will be saved to this file.
backend (Literal['hdf5', 'zarr']) – Backend to use for writing the output file.

Returns:

AnnData – The concatenated AnnData object.
