Dear Dr Weber,
Sorry, as you probably realised, the 10th paragraph that I wrote contains a
mistake: the formula should have been (V/TR) + 0.5 and not (V/TR) - 0.5!
Thus the paragraph should read:
The situation is complicated by the fact that you have interleaved slices.
Optimising the specification of timings for slice 30 would require you to
use V/TR, but optimising the specification of timings for slice 29 would
require you to use (V/TR) + 0.5, since this image is acquired 'half a TR'
earlier than slice 30.
Sorry about that!
Best wishes,
Richard Perry.
