Comparison between annotation workflows. The candidate set for annotation is derived by filtering the measured masses based on: (A) the metabolic model, (B) databases, and (C) extended metabolic model (EMM). The candidate sets in (A) and (C) are biologically relevant, while candidates in (B) prior to filtering may not all be biologically relevant.
