Summary of per-residue accuracies for SS predictions.

measure	H	E	C
Q_s	82.7	69.3	84.0
$Q_{s}^{p r e}$	84.4	78.9	78.3
MC	0.754	0.674	0.645

Q_s: The number of correctly predicted residues of the SS class s = H, E, C divided by the number of residues in the class in native structures.

$Q_{s}^{p r e}$ : The number of correctly predicted residues of the SS class s = H, E, C divided by the number of residues predicted as the corresponding class.

MC: Matthews' correlation coefficient.
