An example spatial dataset¶
Here, we have a spatial gene expression dataset measured using Visium from Suo22.
This collection contains two parts:
a high-res image of a slice of fetal liver
a single cell expression dataset in .h5ad
img_path = ln.core.datasets.file_tiff_suo22()
img = plt.imread(img_path)
plt.imshow(img)
plt.show()
adata = ln.core.datasets.anndata_suo22_Visium10X()
# subset to the same image
adata = adata[adata.obs["img_id"] == "F121_LP1_4LIV"].copy()

Validate annotations¶
We’ll register the single-cell data and the image as a Collection.

adata,
var_index=bt.Gene.ensembl_gene_id,
categoricals={"sample": ln.ULabel.name},
