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
