Ok ... I am no pulse program expert either, here's what I see ...
The hint is that the outer loop of this pulse program
indicates a count of 64 (i.e. number complex points you
expect in your 15N dimension). AND, immediately inside of
that loop is a 2 x loop with "igrad EA", which is the Echo-AntiEcho
you expect for 15N in this case. SO ... its the Z-axis which is 15N.
Here's a scheme I used on some related pseudo-3D data, maybe it's
enough of a hint to help ... in your case, -zMODE will be Echo-AntiEcho,
and you'll want to rename the planes to sort them in tau order ...
