If you have 2 volumes that share an RAS coordinate system but have different
voxel geometry you can use the -rl ("reslice like") option:
mri_convert -rl template.mgz vol_to_convert.nii vol_like_template.mgz

Subject: [Freesurfer] Reversing mri_convert
External Email - Use Caution
Hi,
I convert orig.mgz -> T1.nii using mri_convert orig.mgz T1.nii
I now have something registered to the T1.nii and would like to move it back to
Freesurfer space. How would you go about doing that? I am assuming I would do
the inverse of the mri_convert, but I can't seem to find the option to write
the matrix.
