Dear Roberto
I think I can answer your problem.. Have you recently picked some
peaks? Aanalysis doesn't let you have peaks in areas of the chemical
shift space which are not mapped to a spectrum. Thus if you click to
make a new peak it expands all spectra with selected peak lists and
expands their limits (aliasing a snecessary) to encompass the new peak.
There is a simple solution goto the menu experiment->edit spectra click
on the spectrum that has expanded and click referencing and then reedit
the minimum aliased frequency and maximum aliased frequency to the
original specturm limits (there really ought to be a reset buttone here)
hope that helps
regards
gary
