I noticed my spectra baseline curve is off on Y-axis (amplitude). Therefore I would like to move the whole spectra a little bit up, so that baseline would be at 0 (at the moment, it is negative).

I tried all preprocessing tools in JMRUI, however I did not find any that would just simply “move” the whole spectra on Y-axis without modifying spectra in any other way. I am kindly asking you for help.

Thank you,
