From: Fold-specific sequence scoring improves protein sequence matching
The ratio of the best average z-scores obtained with the Blosum62 combined with topology-based matrices to the Blosum62 z-score for mixed alpha and beta protein set, for varying cutoff distances for defining sequence matches. The z-scores are obtained for the Blosum62 combined with topology-based matrices for a range of weight coefficients. The maximum (best) z-score for each topology is averaged over the mixed alpha and beta topologies to obtain the best new z-score for the alpha/beta class
