Hello,<br><br>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:<br>

<br>
if I recall correctly &quot;the sliver problem&quot; stems from the use of an incompatible libGL. I did the following that a colleague found out:<br>
add the following line to ${FREESURFER_HOME}/bin/tksurfer (that is the script that calls tksurfer.bin):<br>
setenv LD_PRELOAD ${FREESURFER_HOME}bin/libGL.so.1<br>
<br>
Also unpack the following to reside in your ${FREESURFER_HOME}/bin directory:<br>
<br><br>
<br>
<br>
(Those are GL libraries from a redhat 4 / centos 4 system that seem to work with tksurfer).<br>
<br>
<br>
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).<br>
<br>
ahoi &amp; good luck<br>

Hi, there,<br>
<br>
I am running the tksurfer command to view the cortical surface data as tksurfer bert lh inflated. But I met a problem.<br>
I only can view a sliver part of the brain. This sliver portion can rotate and do everything that tksurfer is supposed to do,<br>
but I can&#39;t view any more of the brain than a tiny piece. Tkmedit works fine.<br>
<br>
When I run the command, it gave me something like this:<br>
<br>
surfer: current subjects dir: /home/m047599/freesurfer-install/freesurfer/subjects<br>
surfer: not in &quot;scripts&quot; dir ==&gt; using cwd for session root<br>

<br>
<br>
I searched the previous posts, it looks like somebody have the same problem.<br>
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.<br>
I ran the xdpyinfo | grep GL, it shows that I have GLX and SGI-GLX.<br>
I ran the glxgrears, it works, although very slow.<br>
2<br>
So, how can I solve this problem, any suggestions are highly appreciated.<br>
<br>
Thanks a lot!<br>
