Metabolomics data processing and analysis. Figure 1: Overview of typical tasks in metabolomics workflows, ranging from metabolite profiling (left, green) via metabolite annotation (center, purple) to data analysis using statistics and metabolite networks (right, red).

Mass spectrometry data handling and (pre-)processing. For all mass spectrometers, the fundamental data generated is a mass spectrum, i.e. mass-signal intensity pairs. MS-based metabolomics data is typically acquired either as a single mass spectrum or a collection of mass spectra over time, with the time axis (retention time) defined by chromatographic (or other time domain).

Batch processing of FTMS mass spectra. All sections discussed so far in this book chapter treated individual mass spectra. However, comparisons between different acquisitions, which represent several samples of different origins or treatments, are required for sample classification and statistical data : Basem Kanawati, Karl Peter Wanczek, Philippe Schmitt-Kopplin.
