Undoubtedly, your 001.mgz has larger voxels, and so there will be some
changes in seg volumes. A better way to do this is with mri_label2vol.
First, you'll need the right registration file. Get that with:
tkregister2 --mov 001.mgz --targ orig.mgz --regheader --reg reg.001.dat
--noedit
Now run mri_label2vol:
mri_label2vol --reg reg.001.dat --seg aseg.mgz --temp 001.mgz --o
aseg-in-001.nii
You will still have changes in volumes, but I think this is the best you
can do

Dear gurus,
when running mri_convert -rt nearest -ot nii -rl 001.mgz
seg_edited.mgz seg_edited_axial.nii to reslice from coronal to axial
space we are seeing some significant volume changes in the
segmentation. Anyone know why or how to fix it.
