mne.spatio_temporal_dist_adjacency#

mne.spatio_temporal_dist_adjacency(src, n_times, dist, verbose=None)[source]#

Compute adjacency from distances in a source space and time instants.

Parameters:

srcinstance of SourceSpaces

The source space must have distances between vertices computed, such that src[‘dist’] exists and is useful. This can be obtained with a call to mne.setup_source_space() with the add_dist=True option.

n_timesint

Number of time points.

distfloat

Maximal geodesic distance (in m) between vertices in the source space to consider neighbors.

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.
