Such an approach works well with data acquired from either LC- or IC-MS analysis, where the molecular ion is left intact during full scan MS. With GC-MS using electron impact (EI) or chemical ionization, the molecular ion is typically fragmented, so these additional approaches are not required to achieve full compound identification. MetPA (Metabolomics Pathway Analysis) is a free and easy-to-use web application designed to perform pathway analysis and visualization of quantitative metabolomic data. The approach would be to interpret the compound fragmentation spectra and propose a rational structure. Structure correlation. MS-Omics provides metabolomics analysis as a fee-for-service for universities and companies working within fields such as biotechnology, pharmacy, and food industry. PCA 2. MS/MS spectra are correlated with a list of searched database structures using their calculated molecular formulae. The article discusses how to choose the analytical techniques, extraction procedures, and methods for data analysis. Once data acquisition is complete, spectral data pre-processing occurs through the following steps: This step involves finding and quantifying all the known and unknown metabolites and extracting all relevant spectral and chromatographic information from them. This online course explores the tools and approaches that are used to process and analyse metabolomics data. De Livera AM(1), Olshansky M, Speed TP. In this chapter, we summarize data preprocessing and data analysis strategies used for analysis of NMR data for metabolomics studies.
