Estimating the quality of predicted structural models is a crucial step in homology modeling. Scoring functions analyze different structural features of the protein models in order to generate a quality estimate. QMEAN consists of four statistical potential terms (two non-bonded interaction terms, a torsion angle term and a solvation term) and two components describing the agreement between predicted and observed secondary structure and solvent accessibility.
