This will cluster based on the movement of the ligand with respect to
your last RMS-fit (in this case the backbone atoms of residues 1-441),
which may indeed be what you want. If you want to cluster based on
pocket volume you would need to load that data in and cluster on that
as I previously described. Hope this helps,
