Thanks Stephen. I have run tbss_deproject before with same version of
FSL and OS. I started having this issue several weeks ago. So far I am
able to deproject volumes for one subject. But as in this case, if I
am deprojecting to more than one it throws me these errors. Any
suggestions would be appreciated!
Best,
Steph
