Re: [Freesurfer] use of .m3z transform output from mri_cvs_register

External Email - Use Caution

Hi,

I had mistakenly used the raw moving image in the mri_convert command. It should have been the norm.mgz from the moving subject. The output image from the mri_convert command now perfectly overlaps with the output from mri_cvs_register.

Thanks,

Vinny

Hi,

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,
