Can I use the ROI files for co-registration into the diffusion space and then tractography? Thanks!

That will result in 4 ROI files that you can use in your further analysis.

This is the first time I am doing tractography and my aim is to do it specifically for the cerebellum. I saw online that FreeSurfurer can segment the cerebellum, to create the ROI but I’m not entirely sure how to go about this. So far I have done the pre-processing, co-registration onto diffusion space and created FOD. It would be great if you could give me advice and any feedback about the pipeline. Thanks for your help!
