Hello,
On the first point, it's possible there is some peak picked outside the
"fundamental" region, and therefore Analysis will automatically repeat the
spectrum in that way. Now I just noticed there is no way to turn this
feature off in the graphical interface (there used to be in v1 so this is
an oversight, not the intent). But in addition to turning it off you'll
also have to open the Experiments --> Edit Spectra dialog and choose the
Referencing tab and change the Minimum and Maximum aliased freqs (last two
columns) to being nothing (which means the fundamental region).
Now to turn the peak region extension feature off, type the following at
the python prompt:
>>> top.analysisProject.contourToUnaliased = False
(and save at some point if you want this remembered). Otherwise the min
and max aliased freqs will keep being reset.
On the second point, we're not positive what you are saying, but does the
HNCO have the same shift list as the HSQC? (That is necessary, but I
suspect if I understand what you are saying then that is true.)
