GC × GC–TOFMS chromatographic data for a wild-type strain. Metabolites from five yeast strains (wild type, snf1Δ, adr1Δ, cat8Δ, and adr1Δcat8Δ) were extracted and derivatized for GC analysis as described in “Materials and methods”. The derivatized metabolites were analyzed via GC×GC–TOFMS, with a representative wild-type chromatogram provided here. The complex samples benefit from 2D–GC as the peaks spread out in both GC separation dimensions
