I ran the mri_cvs_register between two subjectIDs with very good alignment between them.  I had assumed that applying the outputted m3z transform, i.e.,final _CVSmorph_toTEMPLATE.m3z, to the moving subjectID (subjb) would normalize it to the target subjectID (subja).  That is, the outputted image would be the same as the output image from mri_cvs_register ,final_CVSmorphed_toTEMPLAT_norm.mgz; however, the resulting image was totally out of alignment to the target subjectID.  This is the command I had utilized to apply the m3z transform to the moving subjectID:

mri_convert -at /home/vinny/Tools/freesurfer/subjects/subjb/cvs/final_CVSmorph_tosubja.m3z subjb.nii.gz subjb-to-subja_morph.nii.gz

Thanks for your help,
