Finding Semirigid Domains in Biomolecules by Clustering Pair-Distance Variations
Figure 6
STDDV captured within clusters decreases with number of clusters. STDDV captured within clusters corresponds to the sum of areas of diagonal, coloured squares in Figure 13, right panel. Values of STDDV were normalized with respect to the total amount of STDDV without clustering () and have been multiplied by (i.e., number of squares) in order to be comparable. Note that the decline roots in the presence of mutual motile dependencies between pairs of atoms. If there were no depencencies, increasing the number of clusters would not significantly reduce STDDV, as demonstrated by the comparison with randomized dependencies shown in Figure 13.
