The previous mining phase discovers a collection of frequent (minLink = 1) SOAPs and the associated episodes in each trajectory. Therefore, it identifies all the conformations in the trajectories that contain at least one frequent (minLink = 1) SOAPs. For instance, the last conformation in trajectory T23 (Figure 1(c)) has two SOAPs of size 2:(5 8) (i.e., association of a type 5 and a type 8 bit-pattern) and (7 8), and three SOAPs of size 1: (5), (7), and (8), while the last conformation in trajectory T24 has three SOAPs: (7 8), (7) and (8). This leads to our SOAP-based approach for folding trajectory summarization.
