Cellphonedb: inferring cell–cell communication from combined expression of multi-subunit ligand–receptor complexes.obsp: 'connectivities', 'distances'. We can compute the Moran’s I score with squidpy.gr.spatial_autocorr and mode = 'moran'. We first need to compute a spatial graph with squidpy.gr.spatial_neighbors. We will also subset the number of genes to evaluate. We can visualize some of those genes with squidpy.pl.spatial_scatter.SpatialData has a more complex structure than the (legacy) spatial AnnData format introduced by squidpy.Nevertheless, because it fundamentally uses AnnData as table for annotating regions, with some minor adjustments we can readily use any tool from the scverse ecosystem (squidpy included) to perform downstream analysis. Tutorials. Vizgen Mouse Liver Squidpy Vignette. Vizgen Mouse Liver Squidpy Vignette. This vignette shows how to use Squidpy and Scanpy to analyze MERFISH data from the Vizgen MERFISH Mouse Liver Map.
