Squidpy.

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. Things To Know About Squidpy.

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. squidpy.datasets. slideseqv2 (path = None, ** kwargs) Pre-processed SlideseqV2 dataset from Stickles et al .

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. There was an issue with indexing but installing squidpy from main should fix the metadata not populating. The spatial coordinates are being populated by the center_x and center_y from the metadata. The sq.read.vizgen function doesn't use the cell segmentation output, either the older hdf5 or the newer parquet formats.

Install Squidpy by running: pip install squidpy. Alternatively, to include all dependencies, such as the interactive image viewer napari, run: pip install 'squidpy[interactive]'
