Hi,<br><br>We are operating x86_64 redhat linux on a server, and we recently installed FreeSurfer on the surfer to help with running multiple recon-all&#39;s.  However, whenever I attempt to run tkmedit or tksurfer, I get the following error:<br>
<br>[andrew@scan2 Anatomicals]$ tkmedit Focus_reg_009 brainmask.mgz<br>GLUT: Fatal Error in tkmedit.bin: OpenGL GLX extension not surrported by display:<br> :1.0<br><br>Is this a problem specific to the VNC Viewer I am using (Chicken of the VNC on a Mac OS X), or some other compilation problem?<br>
<br>Thanks!<br><br>-Andrew<br>
