Discriminant of SCOP superfamily 7.3.5 in the WCM space. Word correlation matrix representation of the discriminant weight vector of superfamily 7.3.5 (omega toxin-like) after training using K = 6 (see text). Rows and columns correspond to occurrences of amino acids at two particular word positions for the first and second occurrence, respectively. Red (blue) matrix elements represent large positive (negative) discriminant weight values according to the color bar on the right hand side.
