I am trying to transform the volumetric labels from aseg.auto to the original space. As suggested on the wiki I use the command
mri_label2vol --seg aseg.mgz --temp rawavg.mgz --o aseg-in-rawavg.mgz --regheader aseg.mgz
However, I got ERROR: Option --regheader unknown
If I don't use that option at all, the image is still in coronal orientation although the header is changed to axial. Would you please help me on this?
