The Image Container is an object for microscopy(微观) tissue images associated with spatial molecular datasets(可见Image Container是对图片和数据进行联合处理的这样一个软件).Squidpy provides other descriptive statistics of the spatial graph. For instance, the interaction matrix, which counts the number of edges that each cluster share with all the others. This score can be computed with the function squidpy.gr.interaction_matrix(). We can visualize the results with squidpy.pl.interaction_matrix().If each sample has all the 13 clusters, then the color will be right, but when the cluster number is different (such as C7 has 12 clusters, while C8 and C6 has 13 clusters, the color will be disordered. It seems that squidpy assign leiden colors by the sequence of the color, not the cluster names. I think It is the case in scanpy and squidpy.This example shows how to use squidpy.pl.spatial_scatter to plot annotations and features stored in anndata.AnnData.

By default, squidpy.im.process processes the entire input image at once. In the case of high-resolution tissue slides however, the images might be too big to fit in memory and cannot be processed at once. In that case you can use the argument chunks to tile the image in crops of shape chunks, process each crop, and re-assemble the resulting image. Download the data from Vizgen MERFISH Mouse Brain Receptor Dataset. Unpack the .tar.gz file. The dataset contains a MERFISH measurement of a gene panel containing 483 total genes including canonical brain cell type markers, GPCRs, and RTKs measured on 3 full coronal slices across 3 biological replicates. This is one slice of replicate 1. With Squidpy we can investigate spatial variability of gene expression.
