Hi folks.

Does anyone know if it is possible in CNS (I'm using version 1.1) to do
strict NCS refinement ON MORE THAN ONE GROUP?  Doing so for contrained
NCS is a cinch because you specifiy several groups of equivalent

In other words, suppose you have crystal diffraction data for a complex
of two molecules.  If one is a hexamer and the other a tetramer, can you
set up strict NCS for a monomer of each molecule?
