Figure 4From: MetaboHunter: an automatic approach for identification of metabolites from 1H-NMR spectra of complex mixturesComparative performance of metabolite matching strategies applied on individual metabolite spectra with chemical shift variations. Each experimental metabolite spectrum from both reference libraries were altered by adding/subtracting a chemical shift variation from 0.00 ppm to ± 0.05 ppm in equal increments of 0.01 ppm and then searched against both libraries. The percentage of matched metabolites was averaged over 5 iterations.Back to article page
