^aFor classifying a)sequences folding to highly-designable conformations for the hexagonal and triangular shapes against sequences folding to the least designable conformations for these two shapes; b)sequences folding to the most designable conformations of the hexagonal shape against sequences folding to the least designable conformations of the triangular shape and c)sequences folding to the most designable conformations of the triangular shape against sequences folding to the least designable conformations of the hexagonal shape. Prediction accuracy and area under the curve (AUC), sensitivity (Sens) and specificity (Spec) for each method are given.
