Current implementation does bond detection using 3D histograms. For unwrapped trajectories those histograms end up huge and kill the process. Should rethink the implementation or at least throw a warning when performing atomselect on unwrapped trajectories
Speed it up by only doing bond detection when necessary. For example in resid 158 there is no need to calculate the bonds.
