Could it be an issue of folded versus unfolded coordinates?

Maybe the FOLDED coordinates form a nice cluster, but the
unfolded coordinates end up in different cells.  If that is
so, and the radius of gyration is calculated with the unfolded
coordinates, then the answer is pretty much random.

Best,
