Compute adjacency from distances in a source space and time instants.
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
Number of time points.
Maximal geodesic distance (in m) between vertices in the source space to consider neighbors.
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.
