Dear experts,
I'm doing a Matlab script (2016b) to do the preprocessing of brain images in Ubuntu 16.04.
When using the FSL epi_reg function, I get the following error:

FLIRT pre-alignment
Running BBR

Can anybody help me? Do you know what is the reason that causes this error?
Thank you very much in advance.
Best wishes,
Marina.
