Dear CCP4 bulletin boarders,
I've been experiencing problems with the refinement of a structure at a
resolution of 1.9 Å with a ~30% pseudo-translation.
The structure in question is a dimer of dimers (i.e. tetramer.) This is
what is observed in the asu and is correct based on biological
informati
Yes :)
It's a common issue that requires a modicum of planning and dexterity to
overcome:
* cutting is done under a macroscope - it's much easier to see what you're
doing
* firm pressure on the plate (with one hand grasping the sides) is key to
success
* firm downward pressure of the scalpel/razo
Hi.
I was wondering if anyone had advice about removing crystals from 96 well,
3 drop sitting drop trays used for automated crystal screening. Recently,
I was trying to remove crystals from an Intelli-plate designed by Art
Robbins Instruments, which has three small drop wells next to a reservoir.
Quoting Jacob Keller :
Also, in your selenium crystal example, I think there would still be an
anomalous signal, because there would always be regular scattering as
well
as the anomalous effect. Isn't that true?
It is certainly not correct to state that there is no anomalous
scattering in
Hi all,
I know there was some interest in months past pertaining to a
screensaver that would display PDBs. I've just updated my program for
Mac OS X and am pleased to announce its release. Structure 2.0 is
Intel compatible and is much faster and prettier than the previous
version. You can download
A postdoctoral position will be available Fall 2009 in Philadelphia,
PA, USA. The successful candidate will join a collaborative research
effort between the Eckenhoff laboratory at the University of
Pennsylvania and the Loll laboratory at the Drexel University College
of Medicine. This coll
You can do this using coot. Just switch on showing symmetry mates(menu
Draw->Cell&Symmetry). Then save the needed by "Save Symmetry Coordinates
Option" in menu File. Waters coordinates will be saved as well.

You are right ; extremely accurate NCS parallel to a symmetry axis does
distort the plots, but its effect is usually resolution dependent so
expected straight lines are often not straight..
And pseudo NCS translation can be even more confusing.
