Hi!
I did bet for 4D DTI image using FSL4.0
After typed 'bet dti_4d dti_4db -m -f', skull was stripped well.
But 'dti_4db.nii.gz' was no longer 4d image.
Just first image of dti_4d was remained.
The option '-F' did not work for 4d DTI image.
I did bet using both intel Mac and 64-bit linux (FC5) machine.
Same command did work correctly in FSL3.X
thanks,
bs Jeong
