Hi,
We need more information than this to diagnose the error.
Can you send us the exact fsl command-lines that you are running?
And also check if all your images are in "radiological" orientation
as determined by fslorient. This can cause problems if you have
a mix of "radiological" and "neurological".
All the best,
Mark
