mne.spatio_temporal_tris_adjacency#

mne.spatio_temporal_tris_adjacency(tris, n_times, remap_vertices=False, verbose=None)[source]#

Compute adjacency from triangles and time instants.

Parameters:

trisarray

N x 3 array defining triangles.

n_timesint

Number of time points.

remap_verticesbool

Reassign vertex indices based on unique values. Useful to process a subset of triangles. Defaults to False.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns:

adjacencycoo_matrix

The adjacency matrix describing the spatio-temporal graph structure. If N is the number of vertices in the source space, the N first nodes in the graph are the vertices are time 1, the nodes from 2 to 2N are the vertices during time 2, etc.
