Squidpy

The co-occurrence score is defined as: where p ( e x p | c o n d) is the conditional probability of observing a cluster e x p conditioned on the presence of a cluster c o n d, whereas p ( e x p) is the probability of observing e x p in the radius size of interest. The score is computed across increasing radii size around each cell in the tissue.

We would like to show you a description here but the site won’t allow us.Here, we’ll take a look at various spatial statistics implemented in Squidpy [Palla et al., 2022]. 27.2. Environment setup and data# We first load the respective packages needed in this tutorial and the dataset. import scanpy as sc import squidpy as sq sc. settings. verbosity = 3 sc. settings. set_figure_params (dpi = 80, facecolor = "white") 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.
