The squidpy.im.ImageContainer constructor can read in memory numpy.ndarray / xarray.DataArray or on-disk image files. The ImageContainer can store multiple image layers (for example an image and a matching segmentation mask). Images are expected to have at least a x and y dimension, with optional channel and z dimensions.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().eQabOeVcRPPXQLW\-dULYeQVcaOabOeaQaO\VLVRfbRWKVSaWLaOQeLgKbRUKRRdgUaSKaQdLPage, …

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.Here in Squidpy, we do provide some pre-processed (and pre-formatted) datasets, with the module squidpy.datasets but it’s not very useful for the users who need to import their own data. In this tutorial, we will showcase how spatial data are stored in anndata.AnnData.

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. 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.The spatial coordinates of the spots will be the same among different samples, so I wanna the ways that squidpy process this kind of object. In fact, all the downstream analysis, such moranI, ripleyL, co occurrence are related to this kind of problems and this is a question about spatial transcriptome data integration.squidpy.im.calculate_image_features. Calculate image features for all observations in adata. adata ( AnnData) – Annotated data object. img ( ImageContainer) – High-resolution image. layer ( Optional[str]) – Image layer in img that should be processed.

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 .The tissue image in this dataset contains four fluorescence stains. The first one is DAPI, which we will use for the nuclei-segmentation. crop.show("image", channelwise=True) We segment the image with squidpy.im.segment using watershed segmentation ( method = 'watershed' ).
