Such a "twinning operator" can also indicate that you spacegroup has an
extra symmetry operator (h,-h-k,-l)
That is in fact one of the symmetry operators for P3i21 H32 P6i22
Have you solved the structure in the lower symmetry and is that missing
density properly generated by this operator?
Dear all,
I am trying to solve the structure of a protein complex, via MR, and when the
phasing is complete there is 1/3 of the unit cell that is missing electron
density. The density present looks very good and shows helices in regions that
were disordered in my NMR model, suggesting that it
