The frequencies of μ
sampled during the search for proteins with native structure PDB ids 1ail and 1isuA are shown in (a) and (c), respectively. Frequency of lRMSDs to the native structure for each protein are given in (b) and (d), respectively. The solid red line represents BH employing the unbiased perturbation method. The dashed lines represent BH with median perturbation distances D = 1Å to D = 5Å.
