Oh, sorry, should have read to the end of my inbox before responding.  What does ls -l show for that file?

Hi Ruopeng,

 

This is the command I have been using: freeview tutorial_data_20190918_1558/diffusion_recons/Diff001/mri/brainmask.mgz

 

I get the same result when I open freeview and select the volume through the GUI.

Can you post the full freeview command that you ran?

Hi, I am using FreeSurfer 7.3.2 with Ubuntu 20.04.4 LTS. I have an issue where Freeview crashes with a segmentation fault when loading a .mgz volume file. The files I have been trying to open are part of the tutorial dataset.
