I am using MRtrix to reconstruct a tract from the HCP dataset. I already tried a single subject and everything works well. The problem is that the tract requires specific manual ROIs. Drawing those for 900 subjects doesn’t make sense. Does anybody know of a way to transfer ROIs into each subject’s space with existing transformation matrices in HCP? I could either draw the ROIs in template space or use the ROIs I drew for the single subject to push them in the space of all the other subjects.
Any help is appreciated.
