Dear all,

I wanted to open qdec for the first time and experienced an error that was posted some days ago...
( RE: [Freesurfer] qdec ERROR: Rendering vtkXOpenGLRenderWindow ; Juranek, Jenifer )


" ERROR: In /usr/pubsw/packages/vtk/5.0.4/src/VTK/Rendering/vtkXOpenGLRenderWindow.cxx, line 219 vtkXOpenGLRenderWindow (0x49220f0): Could not find a decent visual"

In contrast to the previously reported incident, I was finally able to open qdec by just clicking 'ok' on 3 of those exact same error messages. Still - I could not read in any .dat files.....

 I tried to follow the advice given in the previous threat

" In the file /etc/X11/xorg.conf, within the section titled Section
"Module", make sure this line exists:

  Load "glx"

You might need to have your administrator perform this change, as it
requires root access.  You will have to restart your X server after
making this change (Ctrl-Bksp)."

..but I don’t have the referred file in the X11 folder (xorg.conf).

FYI, I’m using the latest Freesurfer version and for a colleague of mine qdec works without having that xorg.conf file..... It is possible that there is any other reason for the qdec error?

Thanks,
Dorit
