mne.spatio_temporal_src_adjacency

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

Compute adjacency for a source space activation over time.

Parameters
srcinstance of SourceSpaces

The source space. It can be a surface source space or a volume source space.

n_timesint

Number of time instants.

distfloat, or None

Maximal geodesic distance (in m) between vertices in the source space to consider neighbors. If None, immediate neighbors are extracted from an ico surface.

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.
