Bob,
This is exactly the confusion. I think
I want the "after" curve in this case
to appear as if it was sampling the same
theoretical curve as the "before" curve,
but sampling it at an earlier timepoint.
If I take a curve and sample it once and
then sample it again at earlier timepoints
and then superimpose them on top of each
other the curve that was sampled earlier
should appear to be shifted to the right
(later) than the curve sampled later.
For the slice time correction to an
earlier slice, do I want the curve shifted
back, or do I want points sampled earlier ?
thanks
kate
