In this tutorial, we show how you can use the squidpy.im.ImageContainer object to train a ResNet model to predict cluster labels of spots. This is a general approach that can be easily extended to a variety of supervised, self-supervised or unsupervised tasks.Squidpy is a Python package for image analysis, such as segmentation, registration, and visualization. Learn how to install Squidpy from PyPI, Conda, or GitHub, and how to use the interactive image viewer napari.

With Squidpy we can investigate spatial variability of gene expression. This is an example of a function that only supports 2D data. squidpy.gr.spatial_autocorr() conveniently wraps two spatial autocorrelation statistics: Moran’s I and Geary’s C. They provide a score on the degree of spatial variability of gene expression.Squidpy provides efficient infrastructure and numerous analysis methods that allow to efficiently store, manipulate and interactively visualize spatial omics data. Squidpy is …Each nanostring sample has different number of FOVs, how should consider setting the ‘library_id’ parameter in this case. Ref - [Use z-stacks with ImageContainer — squidpy documentation] I would highly appreciate any guidance on ways to merge multiple nanostring cosmx objects. Thanks!

Squidpy 20 is another widely used Python package for spatial omics data analysis, analogous to Scanpy. Its main functions include spatially related functions such as spatial neighborhood analysis ...

Squidpy is a tool for analysis and visualization of spatial molecular data.29.3. Moran’s I score in Squidpy#. One approach for the identification of spatially variable genes is the Moran’s I score, a measure of spatial autocorrelation (correlation of signal, such as gene expression, in observations close in space).Both the H&E Visium tutorial and the Import spatial data in AnnData and Squidpy tutorials aren't informative on how to make the image container object after processing the 10X data yourself and having 1 processed anndata file from it. The tutorial for loading the anndata writes an original image.This example shows how to use squidpy.pl.spatial_scatter to plot annotations and features stored in anndata.AnnData. This plotting is useful when points and underlying image are available. See also. See {doc}`plot_segment` for segmentation. masks. import anndata as ad import scanpy as sc import squidpy as sq adata = sq.datasets.visium_hne_adata()squidpy.pl.spatial_scatter closely resembles scanpy.pl.spatial but it provides additional functionalities. For instance, with the `shape ` argument it’s possible to plot polygons such as square or hexagons, a useful feature when technologies other than Visium are used, such as Dbit-seq.Furthermore, it’s also possible to plot a scale bar, where size and pixel units …

SpatialData has a more complex structure than the (legacy) spatial AnnData format introduced by squidpy.Nevertheless, because it fundamentally uses AnnData as table for annotating regions, with some minor adjustments we can readily use any tool from the scverse ecosystem (squidpy included) to perform downstream analysis.

Squidpy implements three variations of the Ripley statistic Fig. 1 (L, F and G; Supplementary Fig. 2b provides an additional example) that allows one to gain a global understanding of spatial pattern-We use squidpy.im.segment with method = 'watershed' to do the segmentation.
