The NIH Common Fund's National Metabolomics Data Repository (NMDR) is now accepting metabolomics data for small and large studies on cells, tissues and organisms via the Metabolomics Workbench. We can accommodate a variety of metabolite analyses, including, but not limited to MS and NMR. In order to ensure reproducibility and interoperable use of data, we require experimental metadata (see tutorials) to be deposited along with the metabolite measurements. Processed data (measurements) maybe in the form of quantitated metabolite concentrations, MS peak height/area values, LC retention times, NMR binned areas, etc. Raw data in the form of MS and NMR binary files and associated parameter files may also be uploaded. We accept data from both targeted and untargeted studies. The Metabolomics Workbench also provides a suite of tools for analysis and visualization of the data. Step-by-step instructions for the whole process are provided on our Upload and Manage Experimental Data and Metadata page.

Experimental data curated by the NMDR is available for searching and analysis, via online interfaces. Users may also search the Metabolomics Workbench Metabolite Database, which now contains over 164,000 discrete structures and the RefMet database which provides a standardized reference nomenclature for both discrete metabolite structures and isobaric species identified by MS and NMR techniques in metabolomics experiments. An up-to-date summary of assets in NMDR is available (it takes about 20 seconds).
