Fig. 3 — The ratio of the best average z-scores obtained for the Blosum62 combined with topology-based matrices to the Blosum62 z-score for all beta sheet protein set, for varying cutoff distances for defining the sequence match from the structure alignment. The z-scores are obtained for the Blosum62 combined topology-based matrices for a range of weight coefficients. The maximum (best) z-score for each topology is averaged over all beta sheet topologies to obtain the best new z-score for the all beta sheet class
