Hi Jon,

phenix.refine has NCS restraints, which you can make as strong as you like by playing with corresponding weights.

phenix.refine does not have NCS constraints, which is:
- I realize extremely important for refinement of virus structures.
- not the same as "very strict" NCS restrains (although I believe it may be very close).

Implementing NCS constraints it's not in my to-do list.. May be Ralf can comment some more. We probably need to discuss this internally to decide who and when will do it.

  Are there plans to implement STRICT NCS refinement in Phenix ??
  For virus structures I am stuck with using CNS.

   Thanks
