  1. Selected prediction rules found as a by-product of cross-training SCOP and PROSITE. Top panel shows rules probabilistically predicting the PROSITE domain/signature given the SCOP superfamily, while the bottom panel shows rules predicting SCOP superfamily given the PROSITE domains. DOT ('.') links parent class to child class in SCOP hierarchy. The bold value following each rule is the probabilistic weighted score found using cross training.
