nichepca.graph_construction.distance_graph(adata, radius=50, obsm_key='spatial', remove_self_loops=False, p=2, verbose=True, return_graph=False)

Construct a spatial graph based on a distance threshold.

Parameters:

• adata (AnnData) – Annotated data object.

• radius (float (default: 50)) – Radius for the distance threshold.

• obsm_key (str (default: 'spatial')) – Key in obsm attribute where the spatial data is stored.

• remove_self_loops (bool (default: False)) – Whether to remove self-loops.

• p (int (default: 2)) – The norm to calculate the distance.

• verbose (bool (default: True)) – Whether to print graph statistics.

• return_graph (bool, default False) – Whether to return the graph instead of storing it in adata.

Returns:

None
