Dear CCP4
I have data that is twinned with an L statistic of 0.43. It seems all the
crystals that I produced were twinned sadly. Is there anything I can do to
twinned data to make it easier to analyse?
I have tried to use the detwin software but it won't let me input a
twinning operator for a
Dear Careina,
if 0.43 is the twin fraction, you might not be able to detwin your data,
since the twin fraction is very close to 0.5. If you plan to solve your
structure with molecular replacement, I would just run the molecular
replacement with the twinned data and refine the structure with
Nobel Prize Quips: Explore the structure of B2AR bound to its G-protein.
Today, Nobel Laureates Robert J. Lefkowitz and Brian K. Kobilka take
center stage in Stockholm where they will receive their Nobel Prize
Medals for their studies of G-protein--coupled receptors (GPCRs).
To mark this
Dear Careina,
Could you please let us know what your cell parameters are?
And what is the twin law ('transformation') that you suspect?
Best wishes,
Sergei

We are offering RapiData 2013, the fifteenth offering of our popular
course:
Rapid Data Collection and Structure Solving at the NSLS: A Practical
Course in Macromolecular X-Ray Diffraction Measurement
The course will be held 21-26 April 2013: http://www.bnl.gov/RapiData/.
Dear colleagues,
further to Ronan's email I would like to let you know that the programme for
the Diamond MX User Meeting taking place Thursday 3 January 2013 is now
available at:

We look forward to seeing you there.
Best regards,
Dear CCP4 Bulletin Board,
Does anyone have a keybinding I can add to my .coot file so that I can hit
a key (for example, Shift-F) to fix in place the actively selected atom,
without having to go through the fixed atoms dialog box? Also, does anyone
have a keybinding for Clear Fixed Atoms?
off the top of my head (i.e. not tested):
(add-key-binding fix atom F
(lambda () (mark-atom-as-fixed (car (active-residue)) (cdr
(active-residue)) 1)))
(add-key-binding clear fixed atoms D
(lambda () (clear-fixed-atoms-all)))
From: CCP4 bulletin board
There is no easy way to do this.
Both active-residue and closest-atom return the CA of a residue if a CA
exists in the residue. Most of the time that is a reasonable thing to
do. Not here though :-(
Paul.

Dear CCP4 Users,
A CCP4 update has just been released, consisting of the following changes:
* QtRView: A new results viewer with graphs and launchers for Coot, CCP4MG and
ViewHKL
* Nautilus: Added a missing template pdb-file
* Hgen: Bug fix in task interface
* Acorn: Bug fix in task interface
*
I am experimenting with ALMN cross-rotation using some old known structures.
I was surprised to see what seems to be a requirement for the cell dimensions
of the two crystals to be the same. Is that the case?

hello everyone,
I have collected data on a problematic crystal. (first mistake...)
Images spanning phi angles 45-80 look ok and usable, also images 229-279 are
usable (index well and merge well too).
How can I combine the 2 separate .mtz files from Mosflm when I scale them?

Thanks for all the suggestions on and off BB.
I used the GUI Sort/Reindex to combine 6 sections then ran Pointless and Scala.
Got a data set to 2.6A Rmerge 0.12 (0.06 inner shell) and solved it in C2221.
It is a good night!
