For whatever its worth, I think I may have found an inaccuracy in the SPM99
manual. On page 29 there is an option listed to correct for non-sphericity.
Having looked though past emails and discussed it with Tom Nicols, I
understand that this option really doesn't exist in the current SPM package
(although I understand there is some planning for this in the next release).
So, unless told otherwise, I will end my fruitless search for the hidden
correction! (And maybe the manual could be fixed.)
Cheers,
David Kareken
