About: The MANA Summer Symposium 2021, “Novel Analytical Strategies for Scoring Confidence in Compound Annotation,” brought together leading experts to address critical challenges in untargeted metabolomics and lipidomics data interpretation. As current workflows often rely on precursor mass accuracy and MS/MS spectral matching, the symposium explored limitations in these approaches, including uncertainties in false discovery rates driven by adduct formation, retention time variability, and in-source fragmentation. Through expert presentations, the symposium highlighted emerging strategies to improve annotation confidence, including the integration of complementary data such as ion mobility (CCS), as well as the use of chemical and biological context from databases, genetic information, and literature. Together, these discussions emphasized advancing more reliable and biologically meaningful metabolite identification.
