There are many things you can do. None can tell if something 's worth doing
or not but you. Notwithstanding, I wouldn't look for common clusters but I
would compare the predominant cluster representatives in the apo and holo
simulation to identify induced fit conformational changes in the ligand
binding region.

Vague statement. Cannot make conclusions without cluster numbers and
populations.
