Squidpy.

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.

Nuclei segmentation using Cellpose. In this tutorial we show how we can use the anatomical segmentation algorithm Cellpose in squidpy.im.segment for nuclei segmentation. Cellpose Stringer, Carsen, et al. (2021), ( code) is a novel anatomical segmentation algorithm. To use it in this example, we need to install it first via: pip install cellpose .

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.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.We can compute the Ripley’s L function with squidpy.gr.ripley() . Results can be visualized with squidpy.pl.ripley(). We can further visualize tissue organization in spatial coordinates with squidpy.pl.spatial_scatter(). There are also 2 other Ripley’s statistics available (that are closely related): mode = 'F' and mode = 'G'.This plotting is useful when segmentation masks and underlying image are available.
