The data used here was obtained from [ Stickels et al., 2020] . We provide a pre-processed subset of the data, in anndata.AnnData format. We would like to thank @tudaga for providing cell-type level annotation. For details on how it was pre-processed, please refer to ... 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.

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. squidpy.pl.spatial_segment. Plot spatial omics data with segmentation masks on top. Argument seg_cell_id in anndata.AnnData.obs controls unique segmentation mask’s ids to be plotted. By default, 'segmentation', seg_key for the segmentation and 'hires' for the image is attempted. Use seg_key to display the image in the background.While a college degree still pays off, earnings for recent grads is in a slump — and some college majors have high unemployment rates.
