Hi Andy,
what is the slice orientation of the analyze files - axial, sagittal,
coronal? Which of these orientations is the y direction?
The default Analyze volume is radiological orientation, that is +XYZ = RAS
(right, anterior, superior).
Maybe you can use AIR to flip the volumes, just in Y.
If you use mricro and AIR, you could evaluate the orientation problem for
one EPI volume and then develop a script to apply it to all of them.
Kind regards, Darren
PS, My apologies to the FSL team for butting in. You can probably do this
stuff with avwutils?
