Dear experts,
I'm trying to run tractography with 3dTrackID using a ROI map in tlrc space, but my DWI and all another scalar maps are in subject space (they are all output from TORTOISE).
Would you recommend warping the ROI map to the individual subject space, or transforming the DWI etc to Talairach space? For the latter, how can I rotate the Bmatrix or gradient files along with the image files?
Thank you!
