| length: | list of length of significant intervals for each channel pair stored in a cell {channel, channel}. |
| Agg: | aggregated graph showing the frequency of all connections over the whole interval in a matrix [channel, channel]. |
| bet: | temporal betweenness centrality in a matrix [timepoint, channel]. |
| hub: | temporal hub nodes, i.e. nodes with highest betweenness centrality, in a matrix [timepoint, 2]. |
| clusters: | clusters assignment for each channel and timepoint [channel, timepoints]. |
