Hi and thanks for your reply,
I should clarify that the original voxel dimensions of the DTI were .208x.208x1.1. I can reslice to 3x3x3.3 or I could do this entirely proportionally. That would give big voxels in the slice dimension, but would at least be scaled properly. My assumption is that the latter is correct. I assume that I also should redefine the voxel sizes for the template (derived from higher res images) as appropriate.
Am I on the right track?
