Pre-processing NMR functionalities include Bruker bucketing and integration, several normalization methods (Total intensity, quantitative variable and Probabilistic Quotient Normalization).
Figure: NMR spectra bucketing and normalization. Files resulting from upstream pre-processing with the TopSpin software (left) can be imported into W4M for bucketing and integration (NMR bucketing module; right), followed by normalization (NMR normalization module), and subsequently analyzed with the statistical modules.
