I have an experimental spectra with a nonlinear x axis due to uniques detector calibration and a synthetic spectra with a linear x axis. I would like to subtract one from another, is this possible in origin?

Yes, we have Simple Curve Math

There is also baseline subtraction in Peak Analyzer

On Baseline mode page, choose "Use Existing Dataset"

Thanks, Snow
