what do you mean by "stabilized"? do you mean thermodynamic stability of the
protein fold? there is currently no way of directly calculating that,
thought you might estimate it in some ways (Amber does not do this). Or do
you mean "stabilized" as in less fluctuation? if that's what you want, you
can make that claim using RMSF.
