  1. Errsig is the significant difference margin for each score and is defined as the standard deviation over the square root of the number of proteins. Q3H/E/C and SOVH/E/C values are the specific Q3 and SOV scores of the predicted helix, strand and coil regions, respectively. Q3H_O (Q3E_O and Q3C_O, respectively) represents correctly predicted helix (strand and coil, respectively) residues (percentage of helix observed), and Q3H_P (Q 3E_P and Q3C_P, respectively) represents correctly predicted helix (strand and coil, respectively) residues (percentage of helix predicted).
