A typical workflow of a metabolomics study and KOMICS-relevant tools and databases. The process of data acquisition and preprocessing (a) is required for generating the metabolome data. A working hypothesis is generated by interpreting the metabolome data (b), and the cycle is completed after validating the hypotheses by further analyses (the arrow on the left side). The metabolome data are published in the databases (c) and utilized for preprocessing and data mining. The tools and databases introduced in the main text of this paper are shown in bold face.
