External Email - Use Caution        


Not sure what happened here, but running Freesurfer on Ubuntu and not getting this error when trying to view volumes:


freeview -v \
mri/T1.mgz \
mri/brainmask.mgz \
mri/wm.mgz:visible=0 \
mri/aseg.mgz:colormap=lut:opacity=0.2 \
-f surf/lh.white:edgecolor=blue \
surf/rh.white:edgecolor=blue \
surf/rh.pial:edgecolor=red \
surf/lh.pial:edgecolor=red \
surf/rh.inflated:visible=0 \
surf/lh.inflated:visible=0



But it get the error:



bash: mri/T1.mgz: Permission denied



No idea why or how to fix this.  I have also tried other subjects but same thing.
