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

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

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.
