The ProtFold-DFG prediction visualization. The best ProtFold-DFG predictor based on the five basic ranking lists is analyzed. The ranking lists generated by DeepSVM-fold (CCM), DeepSVM-fold (PSFM), Fold-LTR-TCP, MotifCNN-fold (CCM) and MotifCNN-fold (PSFM) are visualized in (A–E), respectively. Based on the basic ranking lists, the corresponding DFG is generated (F), and then the PageRank is performed on the DFG to detect the template proteins in DFG sharing the same protein fold with the query protein (G). For these figures, the blue lines and gray lines represent the relationships among proteins. The relationship between two proteins linked by blue line is closer than that linked by gray line. The red lines indicate the final prediction results: the query proteins and the template proteins are predicted to be in the same protein folds. These figures are plotted by using the software tool Gephi [52].
