Pearson’s R correlation coefficients values between AUC ROC and some helix pair features, i.e. spatial distance (RMSD), sequence alignment distance (dist) and helix contact multiplicity. Only Classifiers built using the most informative amino acid properties for a given class are shown. P‐values below 0.05 are shown in bold. *not confirmed by Spearman rank correlation.
