Dear Yannick

check the file difflist in your data set. Does it have the proper increasing
set of numbers. Is the number of lines equal to TD (F1). Do you have file
called Difframp in ../exp/stan/nmr/lists/gp/user (edlist gp) Does it have
the number of correct entries starting with the lowest and ending with the
highest gradient strength that you enter in the dialogue when running the
au program dosy. Th valus are at the very bottom of the file.

You can also run an experiment where the gradient should not change. For
example enter 50% for the beginning and 50% for the end. Then you should
see no amplitude change at all.

Best regards

Clemens

Dear Ryan,

We have tried with another probe and we observe the same problem. If this i=
s related with the gradient amplifier, I think we should also have some tro=
uble with 1D DOSY experiment and this is not the case.
