Re: [phenixbb] pseudo-merohedral twinning or pseudo-symmetry?

Thanks - this is what I was guessing about the beta angle, but forgot to mention. On Fri, Oct 16, 2009 at 7:19 PM, Gino Cingolani wrote:

Laurie,

I had a similar problem. Scaling statistics in P212121 were OK, and - of course - no twinning was detected ... but nothing made sense during refinement. Looking at the data more carefully I found that if one rescales in P21, the b-angle was stably refined to 90.20 with ~30% better Rsym than in orthorhombic. When running xtriage on the P21 data, I found the data were indeed "pseudomerohedrally-twinned" with twinning fraction ~0.38.

Good luck!
