IMHO. if you have P622 apparent symmetry, your true symmetry could be either P6, P321, P312, or if you are unlucky, it is P3 and there are 4 twin domains. So the others are possibly right in suggesting P1 for twinning tests. BW, Gabor On Apr 19 2012, Patrick Loll wrote:
Dumb question here: When one runs the various twinning tests (e.g. phenix.xtriage), is one meant to use data processed in the higher symmetry SG, or the lower symmetry SG?
A concrete example: I can process a data set in a 622 point group w/ reasonable merging statistics, but an abnormally low solvent content raises my suspicions. So do I process as P6, and submit these data to the twinning test? Or do I submit the data processed as P622?
