Dear Nick,
Thanks for the suggestion! I have to admit that I had found it
unlikely that the graphics driver could solve the problem but we
made the download anyway and it has helped!!
Thanks again
Claus

Claus,
It looks like the image is being clipped. I would suggest updating the
graphics driver directly from the NVidia website. On a number of
occasions, I have encountered oddball problems like this with NVidia
cards, that have been fixed with a driver update. It might be
worthwhile to update both machines.

Hello everybody,
Having worked with quite old versions of freesurfer for a long time
we decided recently to install a newer version on two new computers.
Both are running under the 64 bit version of SUSE Linux 10.2, both
have a Dual Opteron processor, they have 6 GB (system 1) or 8 GB
(system 2) and most hardware and software is quite comparable in
my opinion. There is one major difference with the graphic cards,
system 1 has an MSI GEForce 6600, whereas system 2 has an GEForce
FX 7600GS. I'd expect that both cards are more than sufficient
for freesurfer and I doubt that this difference can be the reason
for the difference I have observed but may be some of you have
experienced a similar problem and can help me out.
What's the problem? All analysis steps of the standard procedure
seem to work fine on both systems. However, I see a reproducible
strange problem on system 2 when I try to use tksurfer on the standard
data set (bert) coming with the package (freesurfer-Linux-rh9-stable-
pub-v3.0.5.-full.tar). When I run the command
tkregister bert lh inflated on system 1, everything looks like
expected. But on system 2 something is wrong, the program tells
the number of vertices and faces as usual and the numbers are the same
as on system 2 (as they should, I'm using the same data set).
Nevertheless, the output looks quite different, I'll try to attach
a screenshot. The window shows up as usual and a small part of the
inflated brain is shown at the right edge of the window but the rest
of the brain is never shown. When I rotate this surface the visible
part of the inflated brain is rotated correctly but the rest is always
missing. Can anybody help?
Thanks in advance
Claus
