squidpy.gr.neighbors.KNNBuilder

class squidpy.gr.neighbors.KNNBuilder(n_neighs=6, transform=None, set_diag=False, percentile=None)[source]

Build a generic k-nearest-neighbor spatial graph.

Each observation is connected to its k nearest neighbors. See spatial_neighbors_knn() 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.
