Full Rigaku R-axis IIC Image Plate X-ray diffraction system
We would like to offer a complete macromolecular diffraction system free of
charge to anyone prepared to pay (up-front) the shipping costs from our
laboratory to theirs.
The system consists of a R-axis IIC area detector, Rigaku
really fascinating, bringing back the discussion for a repository for your
collected frames.

Detection and analysis of unusual features in the structural model and
Hi Fellow BBers,
I wish to point out that
a) this is not an April fools joke,
b) but on the other hand it shows (a little buried in the
recommendations, and misspelled AFTER proofing) that people who properly do
catalogue and preserve images actually can fix deposition errors
I don't model zero occupancy in my model. But can't the refinement programs
just treat those atoms with zero occupancy as missing atoms?

This is an unresolved problem, and no real satisfactory solution exists,
because the underlying reasons for zero occupancy can be different.
For people who understand this and look at electron density, it is not a
problem. For users who rely on some graphics program
displaying only atom
Very interesting

Reading the paper from Dr. Hofkristallrat a.D. and the editorial in ActaF, I
must say that besides the rather reasonable demand for journals to include
crystallography experts as referees, Table 1 would have fooled me as referee.
A validation report of the VTF style might not had helped either
Nice paper !
I really wish PDB could have some people to review those important
structures, like paper reviewer. If the coordinate is downloaded for
modeling and docking, people may not check the density and model by
themself. However this is not the worst case, since the original data was
Given a data set (Fobs or Iobs) and atomic model it is not trivial at all
to tell whether they are real or fabricated.
I looked into this problem for quite some time at some point, and developed
my set of criteria that thoroughly attempt to distinguish between fake and
real, but they can only be
Bernard went to a lot of work to verify that this structure was wrong, so we
should also thank him for his efforts.
It is good to see someone who has a hunch follow that up and let the rest of us
know about it.
Thanks Bernard!

Keeping Bernard's book as reference, it is the best way.

I still believe Prof. Dr. Hofkristallrat außer Dienst, is written as Bernhard -
unless you are referring to some other guy with a french name Bernard. And the
book indeed is a bible of xtallography.

As one may extrapolate given my recent paper, I have been called names a lot
worse

Enough of this - it
Btw,
Table 1 would have fooled me as referee.
Not if the bulk solvent parameters would be reported or validated. See
recommendations.
