Fig. 2From: UmetaFlow: an untargeted metabolomics workflow for high-throughput data processing and analysisRelative quantification of true features for compounds identified in the standard mixtures. Log-transformed fold changes of features in the benchmark list measured by targeted analysis of the QE HF dataset. Compound concentration ratios of the matrix group (Gm) and differential groups (Gd1–Gd6) are specified in Fig. 1 of the paper by Zhucui Li et al. [39]Back to article page
