Hello Muhammad,
From the email thread, it looks like Issue 2 has been resolved. You
just need to tease the signal of the smallest peaks out of the noise,
either by recollecting the data with better S/N or perhaps by some
processing tricks.
Regarding Issue 1:
You did not give any details about TopSpin version or operating system,
but I think I may have an idea why you need to keep running ATMM. You
say that you run ATMM and "save" the values. But do you know for sure
that the file containing the tune/match settings for 29Si have indeed
been saved? I don't remember where those files get stored, but maybe
when it tries to save those settings, you don't have permission to
create and save a new file in that folder. All other existing nuclei
work fine because they already exist.
Does that make sense?
Bob.
