Hi Mahesh,
if you use Refmac, then you can tell it to refine the twin fraction, no need to
tell it the twin law as Refmac will figure it out. If you use phenix, you
explicitly tell it the twin law and refine then with it. You can get the
possible twin laws by running phenix.xtriage and looking
Hello everyone,
I collected a dataset which looked like it is twinned ( or a really long
axis in the cell) and did not process in HKL2000 and MOSFLM but with some
of help and suggestions from CCP4BB, XDS was able to process it. The data
looks good upto 1.7 Å. However, the rfree is stuck at 0.34 e
Hi Omi,
Just to add to Preben's suggestion, something that jumps out from the
conditions you list - those are all fairly chaotropic anions. It might also
be worth looking into other anions from the same end of the Hofmeister
series (i.e. bromide), and possibly chaotropic cations as well.
