Fig. 5.
A and B show diagnostic information on the embedding of the ala12 trajectory frames obtained by pure distance matching, while C and D refer to the results of sketch-map. Similar figures for other dimensionality reduction algorithms are provided in SI Text. In A an C the low-dimensional embedding of the frames is shown, colored according to two of the backbone dihedrals. B and D depict the joint probability distribution of the distances between two frames in high dimension (Rij) and the distance between the corresponding low-dimensional projections, (rij).
