XCMS / Get Spectra using xcmsSet object instead of xcmsRaw object
I am writing a script and need to generate several mass spectra based on a group of peaks that I have in an xcmsSet object. As far as I can tell, however, there only exist methods for generating mass spectra using an xcmsRaw object. I really would like to not have to create additional xcmsRaw objects if at all possible since it takes a LOT of time (especially when processing more than 4 samples and picking peaks using centWave). So, does anyone know how to generate mass spectra using an xcmsSet object or am I out of luck?
Thanks,
Cole Wunderlich
