With Squidpy we can investigate spatial variability of gene expression. This is an example of a function that only supports 2D data. squidpy.gr.spatial_autocorr() conveniently wraps two spatial autocorrelation statistics: Moran’s I and Geary’s C. They provide a score on the degree of spatial variability of gene expression.

Visium datasets contain high-resolution images of the tissue that was used for the gene extraction. Using the function squidpy.im.calculate_image_features you can calculate image features for each Visium spot and create a obs x features matrix in adata that can then be analyzed together with the obs x gene gene expression matrix. By extracting image …Analyze Visium fluorescence data. This tutorial shows how to apply Squidpy image analysis features for the analysis of Visium data.

I provide the scale factor when initialising the ImageContainer, as mentioned in #399.

If each sample has all the 13 clusters, then the color will be right, but when the cluster number is different (such as C7 has 12 clusters, while C8 and C6 has 13 clusters, the color will be disordered. It seems that squidpy assign leiden colors by the sequence of the color, not the cluster names. I think It is the case in scanpy and squidpy.Features.
