Hi, there,

Could you tell me what I need to unpack to solve the "redraw fails" problem?

Thanks a lot!

Guang

...

if I recall correctly "the sliver problem" stems from the use of an incompatible libGL. I did the following that a colleague found out: add the following line to ${FREESURFER_HOME}/bin/tksurfer (that is the script that calls tksurfer.bin): setenv LD_PRELOAD ${FREESURFER_HOME}bin/libGL.so.1

Also unpack the following to reside in your ${FREESURFER_HOME}/bin directory:

(Those are GL libraries from a redhat 4 / centos 4 system that seem to work with tksurfer).

Hi,

it seems that my fix is not universal.. Do you see anything at all? In my case I use NX remote controlling on red hat enterprise linux server with the described fix. NX on 32 bit windows works as does Macosx, only Vista 64bit clients running NX to log into the server fail to use double buffering (they do display everything in tksurfer though just really slow). Hmm, I have no real idea what might be going on there, sorry...

Hello,

I also received the same error message as Guang when trying to run tksurfer. I added the suggested line to $FREESURFER_HOME/bin/ tksurfer and unpacked the files, but I still get the following error message:

I also tried setenv doublebufferflag 0, which also did not work.

Thanks,

Corinna

Nick, do you think it would be possible to make this change for the distribution (it was inspired by your inclusion of libGlut to begin with).

ahoi & good luck Sebastian

Hi, there,

I am running the tksurfer command to view the cortical surface data as tksurfer bert lh inflated. But I met a problem. I only can view a sliver part of the brain. This sliver portion can rotate and do everything that tksurfer is supposed to do, but I can't view any more of the brain than a tiny piece. Tkmedit works fine.

When I run the command, it gave me something like this:

surfer: current subjects dir: /home/m047599/freesurfer-install/ freesurfer/subjects surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /home/m047599/freesurfer-install/freesurfer surfer: Reading header info from /home/m047599/freesurfer-install/ freesurfer/subjects/bert/mri/T1.mgz surfer: vertices=131369, faces=262734 Loading /home/m047599/freesurfer-install/freesurfer/surface_labels.txt surfer: ### redraw failed: no gl window open surfer: single buffered window surfer: tkoInitWindow(bert) surfer: using interface /home/m047599/freesurfer-install/freesurfer/ lib/tcl/tksurfer.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/ tkm_common.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/ tkm_wrappers.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/ fsgdfPlot.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/ tkUtils.tcl Successfully parsed tksurfer.tcl reading white matter vertex locations...

I searched the previous posts, it looks like somebody have the same problem. There is no NVidia and native Linux system on my computer. I run tksurfer on a virtual Linux machine using NX 3. 3. 0. 6. I ran the xdpyinfo | grep GL, it shows that I have GLX and SGI-GLX. I ran the glxgrears, it works, although very slow. 2 So, how can I solve this problem, any suggestions are highly appreciated.

Thanks a lot!
