[MINC-users] mnc2nii, orientation of nii file

Hi,
 I have a coronal MRI that are have re-oriented to x,y,z data-order
with all posetive stepsizes as described by Andrew on
http://brainbody.nottingham.ac.uk/users/wiki/pmwiki.php?n=MincUsersGroup.FAQDataFormats

The directional cosines are othogonal, posetive and increasing in the
size of the dimension (eg 1,0,0 for x).

When I run mnc2nii the resulting nifti files comes out as neurological.
I'd like it to be radiological since FSL seems to not be completely
independent of the voxel data storage order.

Is there something I can do to make mnc2nii output it radiologically?
I thought that reshaping with -xdirection might work but it doesn't.

Alternatively I guess I could change the nii file order+orienteation
using the FSL tools but I'd like to understand why it does not seem
possible with mnc2nii.

Thanks
Soren
