Partial loading

load_anndata_from_partial(...) reconstructs an AnnData from any subset of Xenium outputs.

It can attach:

• MEX counts

• analysis.zarr[.zip] cluster information

• cells.zarr[.zip] spatial centroids

Example

from pyXenium.io import load_anndata_from_partial

adata = load_anndata_from_partial(
    base_url="https://huggingface.co/datasets/hutaobo/pyxenium-gsm9116572/resolve/main",
    analysis_name="analysis.zarr.zip",
    cells_name="cells.zarr.zip",
)

If MEX counts are missing, pyXenium can still return an empty-gene AnnData with cluster and spatial metadata attached when those artifacts are available.
