baseline_corr

baseline_corr

This ‘baseline_corr’ function measures the average amplitude of a region (or regions) which are specified as baseline regions by the user, and then corrects the spectrum so that the average amplitude of these regions is zero. Having baseline corrected spectra is important for noise determination before fitting, although note that poor baseline is often indicative of larger processing or acquisition problems.

To baseline correct a 2D spectrum, while specifying two baseline regions

spec=baseline_corr(spec0,{[80 120 80 120],[80 100 140 160]});
