^aGNM and NMA values are taken from the coarse-grained (Cα) GNM and NMA results reported in Park et al.²⁸

^bValues indicate correlation coefficients, from our own test of GNM, that have significantly increased compared to the values reported by Park et al.²⁸ See Sec. III C for details regarding the calculation of new GNM scores.
