Running mne_analyze

Hello all,

I'm trying to run MNE at MIT and found that mne_analyze will not run (I can
run mne_browse_raw without a problem).

The error message I get is:
Using a 4096-point FFT in filterinf of raw data with 2048-sample tapers
Warning: Cannot convert string
"a-adobe-helvetica-bold-r-normal--14-*-iso8859-1" to type FontStruct
Warning: Cannot convert string
"a-adobe-helvetica-medium-r-normal--14-*-iso8859-1" to type FontStruct
Desired visual not found.

When I try to run mne_analyze through mne_browse_raw, I get the same error
message plus this:
Died child #1 of 1 (mne_analyze, pid = 2796)
mne_analyze terminated. Exit status = 1

Has anyone ever encountered this before?

Thanks,

Kana

hi Kana,

you're likely to have an OpenGL problem. To confirm just start:

mne_opengl_test

are you running MNE via VNC or on a virtual machine? make sure the graphics
are well configured.

Thanks Alex,

Yes, I am running via VNC and it definitely looks like an OpenGL issue..

when I run the test I get:

mne_opengl_test version 1.1 compiled at Sep 30 2010 16:57:05

nvert = 140970
ntri = 281936
Xlib: extension "NV-GLX" missing on display ":42".
GLUT_WINDOW_BUFFER_SIZE 16
GLUT_WINDOW_RED_SIZE 5
GLUT_WINDOW_GREEN_SIZE 6
GLUT_WINDOW_BLUE_SIZE 5
GLUT_WINDOW_DEPTH_SIZE 16
GLUT_WINDOW_ALPHA_SIZE 0
500 x 500

How can I fix this?

Thanks again!

Hi Kana,

Please check out the following page:
http://surfer.nmr.mgh.harvard.edu/fswiki/RemoteAccess?highlight=(glx)

Although, as you are at MIT, it is likely that others have already set this
up. You should ask at your site if anyone is using either FreeSurfer or MNE
with the graphics over vnc or NX. This way you don't have to replicate
setting this up.

HTH,

Thanks!
I will look into this and also ask around.
