Word score profiles for positive test sequences of SCOP superfamily 7.3.5. Word score profiles of the first 5 positive test sequences associated with experiment 1 (SCOP superfamily 7.3.5: omega toxin-like) using word length K = 6. Amino acid sequences are mapped to the x-axis while the y-axis corresponds to discriminative word scores. Word score values are centered at position 4 of the overlapping words. See Equation (12) in section "Discriminant function in feature space" for details about calculation of word scores.
