Hello Freesurfer Developer，

I'm building my own symmetric atlas by Xhemi, something is wrong at the final step(Make final iteration)

Here is my code:

make_average_subject --out myatlas.i3 --surf-reg myatlas.i2.sphere.reg --subjects sub_01 sub_02 --xhemi --lh

When I ran this code, a problem emerged. Here is part of the log:

I run Freesurfer 6.0 on Ubuntu 18.04. I've tried to rerun my script several times but I can't figure this problem out. What could be the possible reasons? Any answer will be appreciated!

Kind regards,
