Hi Emily - Depends on what you're doing. If you're doing an ROI-based or tractography-based analysis, where you extract average FA in a part of white matter, there is no need to warp. If you're doing a voxel-based analysis, obviously all the subjects need to be in a common space to compare their FA values voxel-by-voxel.
