Dear TJ,
I ran into something similar when setting up a SOFAST experiment to run in
ICON. I got the '.../wave/0.0 does not exist' error. It occurred because
Topspin couldn't find the correct shaped pulse from the prosol table when
it ran 'getprosol'. To make it work, I had to add the correct shape,
power, and duration. I also had to modify the prosol relations file
('triple' in my case) to make sure the shaped pulse info (I think both
pulse and power) pointed to the correct line in the prosol table.
Good luck!
Best,
Peter
