Re: CCL:Internal coordinat MD codes



 Hello,
 here are two references regarding minimizations in dihedral space:
  : at : article{fantom,
 title={The program FANTOM for Energy Refinement of Polypeptides and Proteins
 Using a Newton-Raphson Minimizer in Torsion Angle Space},
 author={Thomas Schaumann and Werner Braun and Kurt W"uthrich},
 journal= BIOPOL ,
 volume={29},
 number={},
 pages={679-694},
 year=1990}
  : at : article{fantom2,
 title={Efficient Search for All Low Energy Conformations of Polypeptides by
 Monte Carlo Methods},
 author={Berthold von Freyberg and Werner Braun},
 journal= JCC ,
 volume={12},

 pages={1065-1076},
 year=1991}
 they refer to
  : at : article{dihderiv,
 title={Rapid Calculation of First and Second Derivatives of Conformational
 Energy with Respect to Dihedral Angles for Proteins. General Recurrent
 Equations},
 author={H. Abe and W. Braun and T. Noguti and N. Go},
