The ROC curves of several PSSM based protein encoding methods on benchmark dataset. The receiver operating characteristic (ROC) curves of PSSM-DT and several other existing protein encoding methods were got by testing the models on benchmark dataset through jackknife validation, where the horizontal coordinate X is for the false positive rate or 1-SP and the vertical coordinate Y is for the true positive rate or SN and a good method would yield a curve close to the coordinate (0,1) meaning low false positive rate and high true positive rate.
