Based on these summarized trajectories, we can quickly identify all the conformations where the first α-helix-like or β-turn-like local motifs were formed. For trajectory T23, the first α-helix-like motif was identified in frame 26, and the first β-turn-like local motif was formed in frame 63. For the other trajectory T24, the frames were 29 and 38. This is in accordance with experimental results that α-helices generally fold more rapidly than β-turns. However, since we only consider frequent SOAPs, it is very possible that we might miss the actual first formation of such local motifs. To address this issue, we might need to consider rarely occurring SOAPs. We plan to investigate this in the future. For the two events related to β-turn formation, formation of two extended strands and formation of the turn, we found that for both trajectories, the formation of extended strands preceded the formation of the turn.
