Dear Surfers,
I am trying to launch tksurfer/tkmedit in the stable 5_0_0 environment in the Martinos network, but this fails with glut segmentation errors. FS version 6 tksurfer works on the same machine and data, but I need to create some figures that match version 5. We already tried with a different user and a few years older linux box, same issues. Any suggestions would be greatly appreciated! For example, is there a variable that we could set to point to an older OpenGL version? (My LD_LIBRARY_PATH has not been set, and my PATH does not include anything pointing to /usr/lib or /usr/lib64)
Details:
on machine rukki (locally at terminal):
setenv USE_STABLE_5_0_0 source /usr/local/freesurfer/nmr-stable50-env cd $MY_SUBJECTS_DIR

setenv DISPLAY :0 does not fix the issue (results in GLUT: Fatal Error in tksurfer.bin: could not open display: 0)
I also tried fsaverage4, fsaverage5, fsaverage6, and bert, copied from the same folder into my $SUBJECTS_DIR, same result.
The issue is not specific to tksurfer:
tkmedit -f fsaverage/mri/T1.mgz
