Twinned Data

Hello everybody,

I collected data to 2.8A with the space group P63 but they seems to be twinned. I tried phenix refinement with the twin law I got from Xtriage but the model looks quiet weird...

Hope that somebody can help me with this problem.

Kind regards,

Iris

Hello,

I am afraid that you aren't saying (writing) enough to describe the problem(s) you are facing...

Twin fraction ? How many crystals were used to collect the diffraction data (remember that there are polar space groups, where c going "up" is different from c going "down") etc etc. Without enough information, no advice can be provided...
