Based on the generalized trajectory summarization of BBA5, we identify a consensus partial folding pathway of length 71. In other words, 71 pairs of conformations, one from each trajectory, are considered similar to each other. Figure 3 displays four such pairs along this consensus folding pathway. For instance, the two conformations shown in Figure 3(c), corresponding to the 182th frame in the T23 trajectory and the 116th frame in the T24 trajectory of BBA5 respectively, are considered structurally similar, since both conformations exhibit an α-helix in the left half of the backbone, and a β-turn in the right half.
