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.
