a According to PROCHECK classification.
Stereochemical quality of modeled sprotein structures is calculated by PROCHECK as a fraction of residues assigned to different regions of Ramachandran map. Sprotein models are compared to a set of the best structural matches identified in the CATH library by Fr-TM-align.
