SCR prediction examples. Structural mapping of SCR predictions for (a) d1u9da_ from the Tautomerase/MIF superfamily and (b) d2etja1 from the Ribonuclease H-like superfamily. True positives, false positives, true negatives and false negatives are coloured red, green, yellow and blue, respectively. N- and C-termini are marked. Major secondary structural elements are labelled 'A' for alpha-helices and 'b' for beta-strands
