Dear all I can process my 3.8 A dataset in either P4 or P422 point groups. MR searches and refinement in SG P41 and P41212 results in R/Rfree of around 30/35 % with 8 and 4 NCS copies, respectively. Pointless doesn't seem to complain but Xtriage suggests 25 % twinning in the former (refinement was done without twin law) and that the true point group could be P422. So do I go with P422?
Secondly, where can I find the DIALS equivalent to XDS FRAME.cbf? The statistics are slightly better but I prefer to confirm it visually. I recently had a case of pseudosymmetry which makes me suspicious of automated processing suggestions. Thanks.
