Top three plots: the relative frequency (i.e., conditional probabilities) of Q8, SOV’99, and SOV_refine for eight-state secondary structure for protein pairs from Top8000 having the same and different folds as defined by CATH. Bottom three plots: posterior probability for a given score of Q8, SOV’99, and SOV_refine for eight-state secondary structure when two proteins are in the same and different folds as defined by CATH. More explanations about the meaning of the plots can be found in the caption of Fig. 4
