  1. Ref-set: number of proteins in the reference or training set. Eval-set: number of proteins used to evaluate the performance. Wrange: spectra wave length range. α: alpha helix. β: beta strand. RMSD: root mean square deviation. r: Pearson correlation coefficient. Results for K2D evaluated with 24 proteins are taken from [8].
