Hi Melanie,
thank you for posting the link, it's definitely helping.
Interestingly, there are artefacts in my spectrum (but I won't use it anyway) which seem to interfere with the said getSpectrumNoise() routine ...
As Madeleine pointed out, relax maybe better for this kind of analysis. I'll use that in the future and try to have only perfect-looking spectra without any nasty artefacts.
Cheers
Martin
