Finding Semirigid Domains in Biomolecules by Clustering Pair-Distance Variations
Figure 7
Rigidity versus size of clusters. Black data point refer to clusterings of two trajectories (B4402, B4403), each split into 50 subsections. For each subsection, clustering was performed twice, for and 6, yielding runs of clustering and data points. Optimum solution for is shown in red, for in green (see Figure 5 for 3D visualization of clusters in the protein complexes). Vertical axis: STDDV within clusters was averaged and multiplied by , in order to be comparable. Horizontal axis: normalized cluster size = 1 means that the number of atoms in a cluster exactly matches the average .
