    Each `.h5ad` follows the AnnData spec:
    - `.X` — gene expression matrix (cells × genes), sparse where natural
    - `.obs` — per-cell annotations (see "Metadata" below)
    - `.obsm['spatial']` — `(n_cells, 2)` float32 spatial coordinates
    - (where present) `.layers['count']` — raw integer counts
    - (where present) `.obsm['spatial3d']` — `(n_cells, 3)` float32 (x, y, z=section)
  
    ## Metadata (`obs` columns)
  
    `rep`
  
    ## Notes
  
    Xenium FFPE Human Breast Cancer dataset, 2 technical replicates of Sample 1. Rep1: 167,780 cells × 313 genes; Rep2: 118,752 cells × 313 genes. We ship both the convenient h5ad versions and the original raw outputs (`cell_feature_matrix.h5` + `cells.csv.gz`).
  
    ## Usage
  
    ```python
  

import scanpy as sc from huggingface_hub import snapshot_download d = snapshot_download(repo_id='Shaow/humanbreast_xenium_janesick', repo_type='dataset', allow_patterns='h5ad/*.h5ad') adata_rep1 = sc.read_h5ad(f'{d}/h5ad/adata_xenium_rep1.h5ad') adata_rep2 = sc.read_h5ad(f'{d}/h5ad/adata_xenium_rep2.h5ad')
