It depends on the resolution.

Hi Bruce,
Presumably all that was done to the volume when it was imported was that some zero padding around the sides was added to make it 256x256x256 and the data was reordered. This should not require interpolation to undo, right?
Thanks,
Matt.

Hi Matt,
you can give a -rl <volume name> switch to "reslice like" a template volume. For a parcellation you'll want -interp nearest (or something like that) also.

I am curious about how to use mri_convert to convert wmparc.mgz back to
the
space that the original nii.gz volume that I gave FreeSurfer was in
without
resampling for further analysis with FSL. The volume I imported was 176x208x176, and oriented xorient: Left to Right, yorient: Posterior to Anterior, and zorient: Inferior to Superior. When I run mri_convert wmparc.mgz wmparc.nii.gz I get a file that is 256x256x256, and oriented xorient: Right to Left, yorient: Superior to Inverior, and zorient: Posterior to Anterior. How do I use mri_convert to convert wmparc to the original space without resampling?
Thanks,
Matt.
