--The ranking result of ProtFold-DFG predictor

a: ProtFold-DFG is based on the DeepSVM-fold(CCM), DeepSVM-fold(PSFM), MotifCNN-fold(CCM), MotifCNN-fold(PSFM) and LTR, uses transitive closure and KL-divergence to construct the Directed Fusion Graph and gets the final ranking result through PageRank algorithm;
