iRED analysis between global and internal motion. (a and b) The mode collectivities (k) are plotted versus eigenvalues (λ) from an iRED analysis with rank 2. The separability index (g2) factor, broadly corresponding to the gap between the largest five eigenvectors and the next-largest eigenvalue, is indicated for a representative simulation of ubiquitin (a) and the RBD (b). (c and d) Principal moments of the inertia tensors for the four RBD UNR simulations plotted as a histogram (c) and as a function of time for a representative simulation (d).
