Fig. 2From: Reproducibility of mass spectrometry based metabolomics dataFlow charts of the 3 data sets. Flow charts show the hierarchical structure of the Tech, BioTech and Bio data sets. a The Tech data set is a triple-layered MS-Metabolomics experiment. b The BioTech data set is a double-layered MS-Metabolomics experiment. c The Bio data set is a single-layered MS-Metabolomics experimentBack to article page
