SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides programmatic access to the Metabolomics Workbench REST API to locate metabolite records, standardize names with RefMet, perform m/z and adduct searches, and retrieve study-level experimental data, eliminating manual web searching and inconsistent nomenclature across public NIH metabolomics studies.

Core Features & Use Cases

  • Compound lookups and structures: Retrieve compound details by PubChem CID, InChIKey, registry number, and download structure images or MOL files.
  • RefMet standardization: Match common names to RefMet canonical names, query by formula or InChIKey, and explore hierarchical classifications.
  • Mass-based and spectral searches: Perform moverz m/z searches with specified adducts and tolerances to generate candidate compound lists.
  • Study and experiment retrieval: Search and filter studies by metabolite, analytical method, species, sample source, disease, and download mwTab or JSON experimental data.
  • Gene and protein cross-references: Fetch gene and protein annotations and gene–metabolite associations for pathway or mechanistic follow-up.

Quick Start

Use this skill to standardize the metabolite name glucose with RefMet and return a list of public studies that measure that RefMet entry.

FAQPage Schema
How do I standardize metabolite names to RefMet for NIH public studies?

To standardize metabolite names to RefMet, you query the Metabolomics Workbench REST API to match common chemical names against the RefMet canonical naming system and retrieve standardized identifiers. This eliminates inconsistent nomenclature across public NIH metabolomics studies.

Can I search for metabolite candidates by m/z and adduct type using mass spectrometry data?

Yes, you can perform adduct-aware m/z searches by querying the moverz mass-tolerance endpoint in the Metabolomics Workbench API. You specify the mass-to-charge ratio, adduct type, and tolerance to generate a candidate compound list from mass spectrometry data.

How do I retrieve study metadata and experimental data from the Metabolomics Workbench?

You retrieve study metadata and experimental data by searching the Metabolomics Workbench REST API with filters like species, disease, or analytical method. The API supports downloading full experimental datasets in mwTab or JSON format for further analysis.

What is RefMet standardization and when do I need it for compound identification?

RefMet standardization is the process of mapping common metabolite names to canonical identifiers within the NIH metabolomics framework. You need it for compound identification when cross-referencing metabolites across different public studies to resolve naming inconsistencies.

Does the Metabolomics Workbench API provide gene and protein annotations for metabolites?

Yes, the Metabolomics Workbench API provides gene and protein annotations alongside gene-metabolite associations. You can fetch these cross-references to support pathway analysis or mechanistic follow-up for metabolites identified in NIH public studies.

How do I download compound structures and MOL files using InChIKey or PubChem CID?

You download compound structures and MOL files by querying the Metabolomics Workbench API with identifiers like InChIKey or PubChem CID. The API returns detailed compound records and provides direct access to structure images and MOL file downloads.
