CABS model is a versatile coarse-grained tool for protein modeling, including: de novo folding of small proteins, comparative modeling (especially in cases of poor templates) and structure prediction based on sparse experimental data. As restraints one may use experimental restraints, restraints from templates, or theoretically predicted restraints (for instance predicted side chain - side chain contacts).
Description of the model can be found in:
