Each step of homology modeling must be checked for plausibility. Therefore, errors may be accidentally introduced and spread, protein model verification and evaluation are necessary. The protein model can be evaluated as a whole and individual region. Initially, the folding of the model can be evaluated by the similarity to the template sequence, or the quality of the model can be evaluated using Lamachandran.
