Additional methods passed to prune_vertices


A pruned neuron/neuronlist object


The neuron is plotted initially with all nodes selected (and shown with black points). You can interactively select points to remove (they will now be plotted in red). You can also add points back again (they will return to black). When you are finished, press [e] to exit and then indicate that you have finished (yes).
