try 'coregister' and probably the 'estimate & write' option within 'coregister' (assuming you will do fiber tracking with FSL). All the rest will greatly depend on the remainder of your DTI plans and details of your DWI analysis pipeline, hard to say. Cheers, Bas -------------------------------------------------- Dr. S.F.W.

Now I would like to investigate which tracts are passing through this ROI using some DTI example data from the web. This would require me to transform my ROI nii file to b0 or DWI space. Could this transformation be achieved in SPM and how?
