squidpy.gr.neighbors.RadiusBuilder

class squidpy.gr.neighbors.RadiusBuilder(radius, transform=None, set_diag=False, percentile=None)[source]

Build a generic radius-based spatial graph.

Two observations are connected when their Euclidean distance falls within the specified radius. See spatial_neighbors_radius() for the user-facing API or spatial_neighbors_from_builder() for direct builder usage.

Methods

`build`(coords)
`build_graph`(coords)	Construct raw adjacency and distance matrices.
`combine`(mats, ixs)	Combine per-library results into a single graph.
`postprocessors`()	Return post-build processing steps for `(adj, dst)`.
`uns_params`()	Parameters stored in `anndata.AnnData.uns` after graph construction.
