conpy.connectivity.one_to_all_connectivity_pairs(src_or_fwd, ref_point, min_dist=0)[source]#

Obtain pairs of vertices to compute one-to-all connectivity for.

This is needed for one-to-all connectivity. Calculates all the pairs where the vertex is further away from reference point than the selected distance limit.

Parameters:

src_or_fwdinstance of SourceSpaces | instance of Forward: The source space or forward model to obtain vertex pairs for.
ref_point: int: Index of the vertex that will serve as reference point.
min_dist: float: The minimum distance between vertices (in meters). Defaults to 0.

Returns:

vert_fromndarray, shape (n_pairs,): For each pair, the index of the first vertex. This is always the index of the refence point.
vert_tondarray, shape (n_pairs,): For each pair, the index of the second vertex.
