Untried: if you have Phenix installed: it comes with phenix.probe and phenix.reduce - you could insert the paths to these binaries into the above definitions. | Untried: if you have Phenix installed: it comes with phenix.probe and phenix.reduce - you could insert the paths to these binaries into the above definitions. | ||
== some symmetry mates not shown == | |||
Q: This structure has been solved and refined using phenix in the hexagonal setting of space group R 3. There is one copy per asymmetric unit in R 3. As you can see from the attached image, coot is rendering some but not all of the symmetry mates. | |||
A: Turn up the radius a bit and use (set-symmetry-shift-search-size 3) . I would have thought that 2 is big enough, but maybe not in this case. | |||
