Fig. 2. Transition maps for various values of the electric field. Each point represents one state *BCDE, where each of four structures can be either folded (the corresponding bit is 0) or unfolded (the corresponding bit is 1). The color of the points indicates if it is a final state (yellow) or a transition state (red). The thickness of the lines indicates the frequency of the transition between two states. Green color means transition from a folded state (0) to an unfolded state (1), and blue lines the opposite. Striped lines demonstrate transitions in both directions.
