Hello John,
sounds odd. The default settings of SPM5 are relatively robust.
Therefore, some points that may be worth checking that come to my mind:
- The images are (about) in a good position to start with?
- The headers are "fresh" and not full of affine transformation information
from previous operations?
- Is it a scaling/display problem of the result images? (Is the internal
part "zero" or just to dark to give contrast against the skull parts?)
- Have you tried alternative affine registration & regularisation settings?
- Have you segmented one image (of that series/scan type/study) successfully?
