Squidpy is … In Squidpy, we provide a fast re-implementation the popular method CellPhoneDB cellphonedb and extended its database of annotated ligand-receptor interaction pairs with the popular database Omnipath omnipath. You can run the analysis for all clusters pairs, and all genes (in seconds, without leaving this notebook), with squidpy.gr.ligrec. 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. 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..
