a Comparison of the number of isotopic clusters each detected isotopologue appears in for X13CMS (blue) and geoRge (red) software. b Venn diagram of the number of isotopic clusters detected by X13CMS (blue) and geoRge (red) in biological samples, including clusters identical both in length and isotopologue composition (green circle). c PCA plots of the extracted isotopic profiles of unlabelled and labelled wild-type and ∆zwf E.coli strains after processing using X13CMS (left) and geoRge (right)
