Hello everybody,
I collected datasets with a resolution to 2.8A from 3 crystal grown in the
same condition. The space group seems to be P63. Statistic of XSCALE.LP

I tried Xtriage and got the following:
merohedral twin operator
twin law: h,-h-k,-l
Britton plot: 0.423
H-test: 0.439
Maximum Likelihood Method: 0.457
I have a model with the sequence of my protein and did Phaser_MR (Z-score
around 4... I know that this is quiet bad...). This solution I refined with
phenix.refinement using the twin law from Xtriage. Rfree is around 0.44 best
but the model looks weird...
Greetings,
Iris
