Hi Joel,

This plus or minus is a subtle point of confusion. That
does not refer to the sign of the direction of z-coordinates,
but whether the timing matches the order of slices on disk.

So for axial slices, seq-z would be appropriate in either
of 2 cases: where slices are I->S but aquisition times were
actually S->I or the reverse, where slices are S->I but the
aquisition times were I->S. The seq+z case is for when they
match.

Does that seem reasonable?
