Just because you have a high RMSD and changes in secondary structure
this does not mean you have complete unfolding. High RMSD just means
you are far away from whatever your reference structure is. The
protein could just be adopting a different conformation (or set of
conformations). Your best bet is to actually visualize what is
happening to your system with your favorite visualization program. I
often find that observing trajectory data can reveal details that are
easily lost in comparatively simple plots.
