Abstract
Metabolomics is classically defined as the holistic detection of metabolites of a system and usually involves the following multistep workflow: sample preparation, profile recording, data processing and pretreatment, data analysis, metabolite identification and data interpretation. In this chapter, we focus on the later part of the workflow: the preprocessing, pretreatment and data analysis. Thus we will present techniques and approaches that are commonly used for the analysis of metabolomics data. More importantly, we show that the data analysis does not sit in isolation but is instead intimately linked to the experimental steps that have taken place upstream of it. We will demonstrate that this interaction can be used in a beneficial way, by exploring how the knowledge of the experimental steps can inform the correct implementation of statistical techniques and conversely how a better understanding of these interactions can help us to improve the experimental aspects.
