Population template to match existing template

Hi MRtrix3 Community!

Thanks for all the great work.

I created a T1-weighted and FA Template from my subjects using buildtemplateparallel.sh in ANTS. Now, I want to create a template FOD that matches the template initially generated. I have tried using population_template before. However, my worry is that since the population template creates its own template, it might not match the initial templates I have. Is there a way to work around this? Is it advisable to register the output of the population template to the FA Template?

Thanks!
