Fig. 3From: Detecting intermediate protein conformations using algebraic topologyThe hierarchical clustering structure for (a) Calmodulin (1CLL →1CTR) (b) AdK (1AKE →4AKE) (c) GroEL (1SS8 →1SX4). The plot shows the Isomap generated hierarchy (left) and the Spherical PCA hierarchy (right). The clusters are numbered by their RMSD from the end pointBack to article page
