Access #

Here, we have a spatial gene expression dataset measured using Visium from Suo22.

This dataset contains two parts:

  1. a high-res image of a slice of fetal liver

  2. a single cell expression dataset in .h5ad

img_path = ln.dev.datasets.file_tiff_suo22()
img = plt.imread(img_path)
adata = ln.dev.datasets.anndata_suo22_Visium10X()
# subset to the same image
adata = adata[adata.obs["img_id"] == "F121_LP1_4LIV"].copy()
AnnData object with n_obs × n_vars = 3027 × 191

sc.pl.scatter(adata, "array_row", "array_col", color="ENSG00000081237")

We’ll register the single-cell data and the image as a Dataset.
