External Email - Use Caution        

Hello,

As a beginner, I am trying to run freeview -v using tutorial_data by the code below.

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

I am getting an error :Segmentation fault (core dumped)

but it did not produce CORE file. And I've downloaded the tutorial data set before begin and I am sure that set the TUTORIAL_DATA environment 

variable properly as specified on the tutorial data page.

I am using freesurfer version 7.2.0 in CentOS 8.

Any advice would be appreciated!

Thanks,
Yuhui
