Squidpy is a tool for the analysis and visualization of spatial molecular data. It builds on top of scanpy and anndata , from which it inherits modularity and scalability. It provides analysis tools that leverages the spatial coordinates of the data, as well as tissue images if available. This dataset contains cell type annotations in anndata.Anndata.obs which are used for calculation of the neighborhood enrichment. First, we need to compute a connectivity matrix from spatial coordinates. sq.gr.spatial_neighbors(adata) Then we can calculate the neighborhood enrichment score with squidpy.gr.nhood_enrichment(). This section contains various examples from the squidpy.gr module. Compute centrality scores. Compute co-occurrence probability. Compute interaction matrix. Receptor-ligand analysis.
