    ## Files

    - `h5ad/adata_1.h5ad`

• h5ad/adata_2.h5ad

• h5ad/adata_3.h5ad

• h5ad/adata_4.h5ad

    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)
  
    `layer`, `in_tissue`, `array_row`, `array_col`
  
    ## Notes
  
    4 of the 12-slice Maynard atlas (slices 151673–151676), preprocessed as ready-to-load AnnData. `obs['layer']` carries the manual L1–L6 + WM annotation.
  
    ## Usage
  
    ```python
  

import scanpy as sc from huggingface_hub import snapshot_download d = snapshot_download(repo_id='Shaow/dlpfc_visium_4slice', repo_type='dataset') adata_st_list = [sc.read_h5ad(f'{d}/h5ad/adata_{i}.h5ad') for i in range(1, 5)]
