Populating the interactive namespace from numpy and matplotlib
Testing specific hypotheses about inter-node interactions can often be simpler with just a handful of nodes and connectivity created by hand. TVB makes it simple to construct common scenarios.
# Create empty connectivity wm = connectivity.Connectivity() # First weights and distances nor = 4 wm.motif_all_to_all(number_of_regions=nor) # Centers, specify the number of regions, otherwise it'll use a default value. wm.centres_spherical(number_of_regions=nor) # By default, the new regions labels are numeric characters, ie [0, 1, ...] wm.create_region_labels(mode='alphabetic') # But custom region labels can be used wm.region_labels = ['a1', 'b1', 'a2', 'b2'] wm.configure() plot_matrix(wm.weights, connectivity=wm, binary_matrix=True)
