MIA detects and visualizes isotopic enrichment in GC- EI-MS datasets in a non-targeted manner. It provides an easy-to-use graphical user interface that allows for visual mass isotopomer distribution analysis across multiple datasets. MIA helps to reveal changes in metabolic fluxes, visualize metabolic proximity of isotopically enriched compounds and shows the fate of the applied stable isotope labeled tracer.
