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.
