Summary: Stable isotope directed metabolomics is increasingly being used to measure metabolic fluxes in microbial, plant and animal cells. Incorporation of 13C/15N isotopes into a wide range of metabolites is typically determined using gas chromatography-mass spectrometry (GC/MS) or other hyphenated mass spectrometry approaches. The DExSI (Data Extraction for Stable Isotope-labelled metabolites) pipeline is an interactive graphical software package which can be used to rapidly quantitate isotopologues for a wide variety of metabolites detected by GC/MS. DExSI performs automated metabolite annotation, mass and positional isotopomer abundance determination and natural isotope abundance correction. It provides a range of output options and is suitable for high throughput analyses. Availability and implementation: DExSI is available for non-commercial use from: https://github.com/DExSI/DExSI/. For Microsoft Windows 7 or higher (64-bit). Contact: email@example.com or firstname.lastname@example.org. Supplementary information: Supplementary data are available at Bioinformatics online.
