megicparc.functions.compute_distance_matrix

megicparc.functions.compute_distance_matrix(fwd, gamma=0, theta=0, labels=None)

Compute combined distance matrix and sort it.

Parameters

fwdinstance of Forward

The forward solution

gammafloat in [0, 1]

Weight given to the spatial constraints.

thetafloat in [0, 1)

Weight give to the anatomical constraints. If None only the cortico-cortical distance is used

labelslist of Label

Anatomical region used as reference

Returns

sort_distdict

A dictionary containing: sort_dist[‘vals’] : ndarray, shape (n_sources, n_sources-1) Distance matrix, each row sorted in ascending order. sort_dist[‘idx’] : ndarray, shape (n_source, n_sources-1) Indices that would sort the distance matrix
