MVP (Macromolecular Visualization and Processing) is mainly for the illustration and processing of structure-related information which is useful in structure prediction.
MVP-Fit can flexibly move only one domain of the whole model during the fitting process and still keep all the geometric restraints of bond lengths, bond angles and steric clashes for the model.
