Figure 2
Size of clusters of similar model orientations for 20 NMR models of CHFI. Each bar represents one cluster; its height is proportional to the cluster size. A set of the highest peaks of 20 rotation functions is analyzed together. All functions were calculated in the resolution zone 4–10 Å. The three images correspond to a different choice of the angular cutoff distance that defines the separation of clusters: (a) 4.0°, (b) 6.5°, (c) 8.0°. The correct model orientation belongs to the cluster indicated by the arrow.
