Dear Rhys,
I was not aware that twinning is not possible in P6322 however I agree with
Randy’s advise to check the lower symmetry P63 etc.
We were just collecting data which was apparently P6322 (according to automated
DLS processing: pointless) but the cell dimensions and our knowledge of the
256. Xtriage suggested suggested three 2-fold merohedral twin operators
(-h,-k,l; h,-h-k,-l; and –k,-h,-l). I went to lower symmetry (P31) and applied
twinning law (-h,-k,l) during refinement and that reduced by R-factors.

Hi Garib,
This is a side-question. What you just said writing to Abhinav explains
why I have problem of some repulsion between identical ligands with
different tail conformations when I try to refine them at 25% and 25%
occupancy. In my case the overall occupancy of the ligand is not
expe
Hi Jan,
Did you use the TLS refinement for your data? I have had the similar
problem with the multi-group TLS refinement. After the first run the
resulting pdb file contained unreasonably small atomic B factors for
many atoms comparing to the Wilson plot B factor. They seemed to be the

Hi Uli,
When we send our dry shipper from UK to ESRF, Grenoble, via FedEx we
place a following note on the box:
DRY SHIPPER, Non-hazardous, non-toxic, non-flammable, non-

We write the same in the Contents place of the I
