[Camino-users] Problem with dt2nii

[Philip A Cook]

Hi,

MRIcro has not been updated in some time, so it might not read a multidimensional NIFTI file correctly. You could try mricron, which should work. However, it will only display one component at a time. If you open the _dt.nii.gz file, it should ask you which component you want to view (1-6).

But the Tutorials tell me the DTs are exported to a 5-dimensional image with six components .  I could not find the reason for this result. I would be grateful if you could give some suggestions.
