  • Description

    carries out rigid body, tls, restrained or unrestrained refinement against Xray data, or idealisation of a macromolecular structure. It minimises the coordinate parameters to satisfy either a Maximum Likelihood or Least Squares residual. There are options to use different minimization methods. (At the moment only CGMAT is active.) REFMAC also produces an MTZ output file containing weighted coefficients for SigmaA weighted mFo-DFcalc and 2mFo-DFcalc maps, where missing data have been restored.
