RE: HOW TO use the DTI template for registration
I've also been trying to alter the regularisation parameters for the diffeomorphic step which seems to have improved it in that it looks more normal. Please find attached a screen shot of the IIT atlas (left) and the group wise deformably aligned using regularisation parameters 200 times the weaker ones provided.

There are still regions not well aligned with the IIT atlas and the image is quite blurry. We think this is because there is quite a lot of atrophy in the brains, particularly in the caudate as the are huntington's disease patients, and the ventricles are enlarged.

I'd be interested in your opinion on this template and whether you know of ways to factor in brain atrophy when registering into the IIT standard space?

Kind Regards,
Lauren
