Dear Deena,
yes, I have a Mac Pro with an Nvidia FX 4500 running under 10.6.3. For
me, all programs work more or less fine in hardware stereo (Pymol, Coot,
Moloc, Chimera). I've done the following to get it working:
1. Connect the CRT monitor to the first DVI socket of the graphics card
Hi all,
Pseudo translational symmetry problem was detected in my crystal. I am going to
summarize my work on this in presentation and thesis. While some of my
examiners are not crystallographer, and I notice there are several good papers
on this, but I wonder is there any way to present the
When this happens, I firstly suspect that the spacegroup may be
wrong. We had a case where the symmetry was pseudo I4212 but was really
I222 (or was it really I212121) Anyway most of the structure obeyed the
I41212 symmetry but there was a tail which did not..)

Hi ccp4ers,
I am currently trying to process a crystallographic data set from a
20kDa dumbbell shaped protein which was collected on a Bruker Proteum
series detector. The crystal was badly twinned so the Bruker program
CELL_NOW was used to find twin domains within the data. While it
Two suggestions for the data processing:
1) The more recent versions of Pointless (since 1.4.3, and better since 1.4.9)
can read SAINT output and may do a better job than combat
2) You could scale the data in the Bruker programs and import merged data to
CCP4

Hi, Everyone,
Thank you all very much for the nice suggestions. I am trying to reply within
this email.
I agree that the problem may be rooted from the crystal itself, we noticed
during data collection that a wedge of the rotation was very mosaic, HKL2000
was able to pick up the right spots,
Hi Tongqing,
apart from potential space group related issues that the other mentioned
already, I can't really see anything wrong.
Here is how your R-factors compare to the other R-factors for all
similar structures in PDB:
