Hi Doug,
I'm not sure why, but the registration is off. In tkregister2, the "coronal" appears as an axial slice and vice versa, while the sagittal is rotated 90 degrees compared to the target. I did the following: 1. mni152reg --s MAE_06072013 2. tkregister2 --mov /drobo/Documents_corinna_linux/freesurfer_subjects/MAE_06072013/mri/mni152.orig.mgz --targ /usr/share/fsl/5.0/data/standard/MNI152_T1_2mm_brain.nii.gz --reg /drobo/Documents_corinna_linux/freesurfer_subjects/MAE_06072013/mri/mni152.orig.mgz.reg 3. tkregister2 --mov MAE_06072013/hardi/eddy_bet_MAE_06072013_hardi.nii.gz --reg MAE_06072013/register.dat --surf
Up until this point, everything looks good and well registered.
4. mri_matrix_multiply -im MAE_06072013/mri/mni152.orig.mgz.reg -iim MAE_06072013/register.dat -om MAE_06072013/newmnireg.dat

Hi Corinna, once you do #1, you can concatenate the register.dat with the mni152.2mm.reg.dat like this
mri_matrix_multipy -im mnireg.dat -iim register.dat -o newreg.dat
Check tkregister2 --mov dti.nii --targ $FSLDIR/data/standard/MNI152_T1_2mm.nii.gz --reg newreg.dat
mri_vol2vol --mov dti.nii --targ $FSLDIR/data/standard/MNI152_T1_2mm.nii.gz --reg newreg.dat --o dti.in.mni.nii

Hello all, I am wanting to put labels currently in diffusion space into MNI space. Does this make sense or is there a more straight forward way?
- mni152reg the subject's structural into MNI space
- inverse transform the MNI in the the subject's T1 space
- Use bbregister to align the DTI to the T1 space
- inverse transform the MNI into DTI space using mri_vol2vol using the
registration from step 3?
Cheers,
Corinna
