Towards automatic metabolomic profiling of high-resolution one-dimensional proton NMR spectra
Towards automatic metabolomic profiling of high-resolution one-dimensional proton NMR spectra
Abstract Nuclear magnetic resonance (NMR) and Mass Spectroscopy (MS) are the two most common spectroscopic analytical techniques employed in metabolomics. The large spectral datasets generated by NMR and MS are often analyzed using data reduction techniques like Principal Component Analysis (PCA). Although rapid, these methods are susceptible to solvent and matrix effects, high rates of false positives, lack of reproducibility and limited data transferability from one platform to the next....
