Dear Christian, You obviously mean a _non-crystallographic_ trimer -- in a crystallographic trimer the protomers (and their ligands) would be identical by definition. On the other hand, chains related by non-crystallographic symmetry necessarily differ in their environments. As a results of near

Indeed, update 54 from Mar 29 seems to have messed up several monomer definitions and/or their handling in coot (the version distributed with ccp4): - GLU and ASP contain lines referencing GLN and ASN, respectively, preventing coot from finding any chi angles. - For GLN, chi angles appear twice i

I think the problem is related to the term "coherence" being used to describe both the type of *radiation* and the mode of *scattering*. When talking about (xray) radiation, it denotes the phase relationship between photons, and therefore even a monochromatic beam can be incoherent (whereas a po
