Metabolomics, especially large-scale untargeted metabolomics, generate massive amounts of data on a regular basis, which often need to be filtered, screened, analyzed and annotated via a variety of approaches. Data-dependent acquisition (DDA) mode including inclusion and exclusion rules for tandem mass spectrometry (MS) is routinely used to perform such analyses. While parameters of data acquisition are important in these processes, there is a lack of systematic studies of these parameters that can be used in data collection to generate metabolic features for molecular network (MN) analysis on the Global Natural Product Social Molecular Networking platform (GNPS). To explore the key parameters that impacting the formation and quality of MNs, several data acquisition parameters for metabolomic studies were proposed in this study. The influences of MS1 resolution, normalized collision energy (NCE), intensity threshold, exclusion time to GNPS analyses were demonstrated. Moreover, an optimization workflow dedicated to Thermo Scientific QE Hybrid Orbitrap instruments is described, and a comparison of phytochemical contents from two forms of black raspberry extracts were performed based on the GNPS MN results. Overall, we expect this study to provide additional thoughts on developing natural product analysis workflow using GNPS network, and shed some lights to future analyses that utilizing similar instrumental setups.
