Please leave the old context for the discussion in future emails. Only you are paying so much attention to your work that you can be sure of remembering things :-)

If your simulation started with these strands unfolded, then your problem is somewhere else. However, you have to be able to tell us what was the initial conformation, and when your "first trajectory frame" (per last email) happened in the simulation.
