The identification of metabolites by mass spectrometry constitutes a major bottleneck which considerably limits the throughput of metabolomics studies in biomedical or plant research. Here, we present a novel approach to analyze metabolomics data from untargeted, data-independent LC-MS/MS measurements. By integrated analysis of MS¹ abundances and MS/MS spectra, the identification of regulated metabolite families is achieved. This approach offers a global view on metabolic regulation in comparative metabolomics. We implemented our approach in the web application

We provide a specification of the input file format. In the MetFamily publication we demonstrated the usage of MetFamily with UPLC-(-)ESI-SWATH-MS/MS data preprocessed with MS-DIAL. In the input specification, however, we demonstrate the generation of these files with GC-EI-MS data processed with xcms and CAMERA We also analyzed idMSMS spectra and LC-MS/MS spectra from DDA in MetFamily.Download input specification
The MetFamily web application is designed to support researchers in the interpretation of comparative metabolomics studies at the level of metabolite families.
