For developers from the metabolomics or broader community interested in contributing new MetaboApps, we provide resources and documentation. The core infrastructure is accessible through three key repositories. The Streamlit App GNPS2 template (https://github.com/Wang-Bioinformatics-Lab/Template_Streamlit_App) offers a preconfigured template with GNPS2 integration guidelines for a quick start. GNPSDataPackage (https://github.com/Wang-Bioinformatics-Lab/GNPSDataPackage) is a Python library that enables programmatic access to GNPS2 workflow results via task IDs for postprocessing, providing the tools to work directly with analysis outputs (which are mainly CSV tables, MGF spectra files or GraphML network files). For more experienced developers, we recommend the Dash template (https://github.com/Wang-Bioinformatics-Lab/Dash_Multipage_Template), which provides a framework for building multipage applications. Pull requests are evaluated by core GNPS2 developers for code quality, efficiency and infrastructure compatibility. Developers wishing to implement new MetaboApps in GNPS2 should contact the GNPS2 team to initiate the integration and deployment process. Applications are encouraged to include clear documentation and user-friendly interfaces. We thank the...

Agentic AI for Structural Elucidation and Discovery of Drug Metabolites from Mass Spectrometry Data

The majority of chemical signals detected in public metabolomics repositories remain structurally undefined. Large language models (LLMs) are probabilistic systems whose capacity to generate outputs beyond their training data, which can cause hallucinations, makes them also potentially suited to hypothesize structures for molecules that have never been described. We aimed to build a system that could harness this LLM generative capacity combined with domain specific tools/framework to constrain hallucination and produce validated discoveries. We developed a GNPS2 agentic AI system that interprets LC-MS/MS data by integrating spectral alignment, molecular formula inference, rule-based structural enumeration, machine learning-based spectrum prediction, and translates natural language hypotheses from domain experts into dynamically generated analytical workflows. We demonstrate the annotation of unknown drug metabolites from public data guided by chemical hypotheses. The agent predicted, and we experimentally confirmed, a phosphorylated hydroxyzine, an acetaminophen-p-coumaric acid ester, and identified two new oxidative ibuprofen-carnitine conjugates from public repositories. These results demonstrate that LLM-driven agentic reasoning, when combined with domain expertise, can indeed generate experimentally testable structural hypotheses for previously uncharacterized metabolites leveraging pan repository data.

Okay, here are the Thermo #ASMS2026 leak confirmations: - Tribrid Apex (the next Ascend + IRMPD) - Orbitrap Excedion is the downgraded version (240k max res) of the Orbitrap Excedion Pro. The name is going to cause a lot of confusion. Thanks go to my wonderful sources.

The next generation of mass spectrometrists is here in San Diego! Undergrads at #ASMS2026: your community is waiting. Jump into the poster competition, the networking sessions, the evening workshops. Check the reposted material for details. Ask the question you think is “too basic.” It never is. 💪
