Dear Stefan, Congratulations! It seems that you not only have pseudo-translation and pseudo 4-fold symmetry in your diffraction, but also pseudo 8-fold symmetry in your protein molecules! An excellent case to learn a lot about space groups and NCS symmetry. 3) you are right, you might see pseu

[ccp4bb] How to apply "correction factors" for translational NCS in PHASER?

2013-10-22 Thread Niu Tou
Dear All, I have a MR case which may contain two different molecules, ideally 1:1 ratio. Solvent content analysis indicates most likely to be 4~6 hetero molecules. The data shows at least 5 strong translational NCS vectors. When I tried to run PHASER, it always said "correction factors NOT applie
