scanpy.datasets.pbmc68k_reduced()[source]#

Subsampled and processed 68k PBMCs.

PBMC 68k dataset from 10x Genomics.

The original PBMC 68k dataset was preprocessed with steps including normalize_total()[1] and scale(). It was saved keeping only 724 cells and 221 highly variable genes.

The saved file contains the annotation of cell types (key: 'bulk_labels'), UMAP coordinates, louvain clustering and gene rankings based on the bulk_labels.

Return type:

AnnData

Returns:

Annotated data matrix.
