RE LCD monitor for stereo viewing: No. That monitor, which looks like an ordinary 19 LCD monitor, is not capable of stereo viewing. LCD monitors are in general not fast enough for stereo. There are some new technology LCD monitors which claim to be able to do stereo, this is not one of them.

I wish I knew more about OMIT maps, but after testing Kevins procedure (which omits overlapping sphers with perturbation) and SFCHECK (method unknown) I got quite biased results. It is years since I have run the full CNS/Phenix procedure which attempts to remove bias by simulated annealing..

Ian, are you saying that one might need to know some crystallographic theory in order to determine space groups? Or can we simply click a few buttons in a graphical user interface and be done with it? Jim On Mon, 15 Dec 2008, Ian Tickle wrote: But that only means that the SF contribution

Plug the coordinates (x,y,z) and x+tx, Y+ty, z+tz) into the SF equation. If the translation component along c is 0.5 say, then all the 00l reflections for l=2n+1 will be absent. Eleanor Ronald E Stenkamp wrote: Hi. Non-crystallographic symmetry (NCS) doesn't apply to the entire crystal,

But that only means that the SF contribution from that pair of molecules in the unit cell is zero for (00l) l=odd reflections. Depending on the crystallographic symmetry (e.g. if it were 3-fold or higher order) there may be other pairs for which the SF contribution is non-zero for all (00l)

Ian, Your examples may cause more confusion, especially for those beginners with symmetry. In your P222 and P3 cases, an exact NCS (0, 0, 1/2) turns to be an exact crystallographic translation, which reduces the unit cell to a half while the reciprocal unit cell gets doubled. A half of
