The performance of the conformation ensemble approach on the free modelling (FM) targets from CASP8. The input ensembles were sets of server submitted tertiary structure predictions for each FM target during CASP8. L is the sequence length of each target domain. δ is the neighbourhood size in residues. For δ = 1, a prediction is considered correct if a true contact occurs within ± 1 residues of the prediction. The precision of the predictions is shown first with the recall in parentheses.
