Read Visium HD cell-segmentation output and attach geometries + spatial metadata.

参数:

  • path (str or Path) – Path to the cell-segmentation output directory.

  • sample (str, optional) – Sample key stored in adata.uns['spatial']. If None, inferred from path.

  • cell_segmentations_path (str) – Relative path to segmentation GeoJSON.

  • count_h5_path (str) – Relative path to filtered feature-cell matrix (H5).

  • hires_image_path (str) – Relative path to hires tissue image.

  • lowres_image_path (str) – Relative path to lowres tissue image.

  • scalefactors_path (str) – Relative path to scalefactors JSON.

返回:

Cell-level AnnData with obsm['spatial'], segmentation geometry, and spatial image metadata.

返回类型:

anndata.AnnData
