Hi Cat,
If your pseudo-centering actually leads to significant change in your
cumulative intensity distribution, you might have a convincing explanation as
to why the R-values would remain on the high side. I had a pseudo-body centered
case a long time ago
Hi Bashir,
It does look like you have translational pseudo-symmetry. If the translation
vector happens to be body-centering, it could affect your intensity statistics
so that the R-values would never go down as half of your reflections follow the
distribution for centric reflections. I had
Dear Manfred,
In addition to personal preference I think there are some philosophical
differences in what the model actually means. I would argue that what we see in
the density is stronger evidence of the chemical identity than what we believe
we have used as a starting material. After all we
Dear Colleagues,
I would like to bring to your attention a job opening at the Data Management
and Software Centre fo the European Spallation Source in Copenhagen, Denmark.
In this role your main responsibility will be the design and development of a
data processing pipeline optimized for
either myself or Prof. Ryde
(ulf.r...@teokem.lu.se<mailto:ulf.r...@teokem.lu.se>) for questions.
Best regards,

with hydrogens is the element symbol in the last column.

Mike,
You could try rigid body refinement against the weak reflections to
get the position of the molecules right and then normal restrained
refinement against the strong reflections. I had a case like this some
years ago and that helped...

Would it be too much to ask that the person sending the summary email

the even (strong) reflections. In the presence of significant pseudo-
symmetry, the structure is probably never going to refine very well,
at least in terms of R-value, because it is no longer a very good
indicator of structure correctness...
