It doesn't sound like you've got a problem with the conversion.
I suspect that you are just unhappy with the way around that
FSLView is showing the data. This is perfectly fine, as FSLView
chooses to show the data as the scanner acquired it, so that
sagittal, coronal and axial scans look quite different. Each part
of the FSLView window could show any of the views, in any
orientation - that is not a problem. As long as the *labels*
are correctly attached to the views then the nifti file is correct
and you do not need to do any of the things that Todd suggests.
If you want to reorient your image so that FSLView shows it
in the same way that the standard template images are shown
then you can do the following:
and if the result is "RADIOLOGICAL" then do:
fslswapdim MYIMAGE RL PA IS MYIMAGE
fslswapdim MYIMAGE LR PA IS MYIMAGE
This will perform a 90, 180 or 270 degree rotation
on the image to make it display the same way
around as the MNI152 images in FSLView.
I hope this helps.
All the best,
