Section III: Registration
Registration is something you must think about all through the analysis (eg, FEAT has a registration tab at the individual, within-subject, and group levels). However for conceptual clarity we address registration now.
In broad overview registration works as described in Figure
For individual subjects, you may wish to view results on a better-looking (higher-definition) background than the T2* image (Figure III.2). Since you cannot overlay it directly on the T1 image because of the larger number of voxels in T1, you must merge the T2* with the T1 image in FLIRT.
