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?

1. mni152reg the subject's structural into MNI space

2. inverse transform the MNI in the the subject's T1 space

3. Use bbregister to align the DTI to the T1 space

4. inverse transform the MNI into DTI space using mri_vol2vol using the registration from step 3?

Cheers,

Corinna
