Hi Folks,

To follow up Harry's comments. We have a Pilatus 300K on I19 here at
Diamond which is used from time to time for small molecule work.
Processing with XDS has proved to be successful (I can send an example
XDS.INP but you will need to make sure you have a good knowledge of
the experimental geometry.)

If these had been recorded properly with the full CBF format you would
be able to process them with xia2 with XDS, which is what we have been
using here. However Harry's report suggests that this is unlikely to
work. XDS with a correctly crafted input file should work fine.

BTW, in addition to Tim's comments above, I also set DELPHI=30
(relatively arbitrarily) to give enough reflections that the profile
averaging could be useful. We have not tested this substantially
however.

Best wishes,

Graeme
