Hello fsl users,
I'm a beginner on fsl, i installed fsl in ubuntu linux platform , i run
the evaluation tests and everything was ok.
Even though when i tried (to get started with fsl) to run BET SUSAN FAST
FLIRT with the example images of the fsl -feeds i had the following errors:
on BET:

Finished
on SUSAN:

and finally on FLIRT :

Finished
both images "structural" and "stuctural_brain" looked ok when i opened them
with fslview
Can you help me please?
Thanks in advance
Dinos
P.S. i also attached the fsl error report
