RE: HOW TO use the DTI template for registration
HI Konstantinos,

All the steps I've taken before creating the groupwise are as follows:
-Took raw DWI for each subject time point and converted to 4D FSL NIfTI format.
-Corrected for EDDY currents using EDDY.
-Ran DTIFIT for tensor reconstruction.
-Converted DTI into DTITK format.
-Created within-subject template by bootstrapping both time points to the IXI-aging template then using dti_affine_population and dti_diffeomorphic_population.
-Created Group wise template by bootstrapping the 10 within-subject templates to the IXI-aging template then using dti_affine_population and dti_diffeomorphic_population.

I think the format of the image I uploaded only shows one component of the tensor so it looks similar to a T2 weighted image and therefore probably isn't the best way to visualise alignment. I plan to compare the FA maps for each template and registration.
I've attached the FA map for the group wise template before registering to the IIT atlas.

Regards,
Lauren
