I want to do DEN twin-refinement using phenix. For my data phenix.DEN works better than CNS DEN. I want to DEN with twinning. Is there script for adding twinning operator for DEN refinement in phenix

twin_law=h,-k,-l (or whatever the twin law actually is) phenix.den_refine is basically just a derivative of phenix.refine with a few customizations - nearly all of the parameters are identical otherwise, so the phenix.refine documentation should still be valid for most options. -Nat
