Fig. 5From: Interactive exploration of ligand transportation through protein tunnelsEvaluation of the complexity of a trajectory T in point x. The complexity c(x) is determined by tuples (u,v) and (v,w), i.e., their angles α and β, as the segments u, v, and w lie in the neighborhood of x (red). The neighborhood of x contains all points that are closer (along T) to x than to ν Back to article page
