Hi John
it means that the talairach transform that was computed was extremely
unlikely and deemed to be probably incorrect. Frequently this happens if
you start with images (like analyze) that don't contain accurate direction
cosine information. You can check this by bringing one of the volumes in
freeview and checking to make sure that the anatomical directions we show
(e.g. anterior/posterior) correspond to the true anatomy. Sometimes
abnormal anatomiies like huge ventricles can also make it fail, but you
need to figure out which one it is before deciding what to do
cheers
