Wraps xarray.Dataset to store several image layers with the same x, y and z dimensions in one object. Dimensions of stored images are (y, x, z, channels).

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.

This plotting is useful when segmentation masks and underlying image are available. See also.

The co-occurrence score is defined as: where p ( e x p | c o n d) is the conditional probability of observing a cluster e x p conditioned on the presence of a cluster c o n d, whereas p ( e x p) is the probability of observing e x p in the radius size of interest. The score is computed across increasing radii size around each cell in the tissue.

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.squidpy.im.segment() with method = 'watershed' to do the segmentation, use the channel 0 as it is supposed to contain most of the nuclei info for H&E stain calculate segmentation features using:squidpy.pl.extract. Create a temporary anndata.AnnData object for plotting.

First, we need to compute a connectivity matrix from spatial coordinates. sq.gr.spatial_neighbors(adata) Then we can calculate the neighborhood enrichment score with squidpy.gr.nhood_enrichment(). ImageContainer object. This tutorial shows how to use squidpy.im.ImageContainer to interact with image structured data. The ImageContainer is the central object in Squidpy containing the high resolution images. It wraps xarray.Dataset and provides different cropping, processing, and feature extraction functions.

class squidpy.im.ImageContainer(img=None, layer='image', lazy=True, scale=1.0, **kwargs) [source] Container for in memory arrays or on-disk images. Wraps xarray.Dataset to store several image layers with the same x, y and z dimensions in one object. Dimensions of stored images are (y, x, z, channels). 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().Plot co-occurrence probability ratio for each cluster.
