Hi Bob,
Thanks again for the suggestions. I agree it is great to incorporate but there are definitely several technical challenges such as dealing with differing distortions between modalities (i.e. diffusion vs fMRI vs structural) that will make it a bit more challenging , along with system requirements. Maybe limiting it to structural scans with little distortions such as T1/T2/proton density would be a good first step as it may limit the memory usage and be less susceptible to distortions within subject leading to more robust results. I will definitely keep my eye out and test if you decide to go down this route in the future.

Best,
Ajay
