Analysis of contact maps in native structures and top-ranked models. PPVs were calculated for the sets of contacts that were used during folding (1.0 · l top-ranked contacts) with a Cβ distance cutoff of 8 Å in the structures. (a) PPV values for PconsC contacts on native structures (x-axis) against PPVs on the top-ranked models from PconsFold (y-axis). The colours represent TM-scores of models against native structures. (b) Native structure of 1JWQ. Lines represent all predicted contacts. The colour scheme indicates spatial distances of residue pairs in the structure. The PPV is 0.83. (c) Predicted contacts in the top-ranked model for 1JWQ with the same color scheme. This model has a TM-score of 0.62 and a PPV of 0.46
