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

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.
