The six methods in the front of the table are six useful predicting methods for identification of DNA-binding proteins proposed in the past and were demonstrated to have good performance. The results of the six existing predicting methods and the SVM-PSSM-DT were achieved on the dataset PDB186 by their model trained on benchmark dataset. aThe results of iDNA-Prot [16], DNA-Prot [74], DNAbinder[21], DNABIND [34], DNA-Threader [78] and DDPPred [75] were obtained from [75].
