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 .squidpy.pl.spatial_scatter. Plot spatial omics data with data overlayed on top. The plotted shapes (circles, squares or hexagons) have a real “size” with respect to their coordinate space, which can be specified via the size or size_key argument. Use img_key to display the image in the background.Squidpy allows analysis of images in spatial omics analysis workflows. 我们首先来掌握一些基础的知识. 1、什么是Image Container.

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.Receptor-ligand analysis. This example shows how to run the receptor-ligand analysis. It uses an efficient re-implementation of the cellphonedb algorithm which can handle large number of interacting pairs (100k+) and cluster combinations (100+). See Neighbors enrichment analysis for finding cluster neighborhood with squidpy.gr.nhood_enrichment().We use squidpy.im.segment with method = 'watershed' to do the segmentation. Since, opposite to the fluorescence DAPI stain, in the H&E stain nuclei appear darker, we need to indicate to the model that it should treat lower-intensity values as foreground. We do this by specifying the geq = False in the kwargs. The segmented crop is saved in the ...Squidpy reproducibility.
