Commitment probabilities for transient states in atomistic simulations. The probability of being on a transition path given that an excursion from the unfolded (bottom) or native (top) ensemble either reaches or disrupts the indicated topological configuration, respectively. Only excursions that achieve a minimum fraction of the total number of contacts in a topological configuration, , are counted. No data is available in the case of configuration abef for the stricter condition , because no qualifying events were observed in the available simulation trajectories.
