NMRium new features - March 2026

This update introduces a new open file format and a one-command tool to publish NMR datasets to Zenodo.

1. A new file format: .nmrium.zip. Your NMR data should never be trapped in a proprietary format. NMRium now saves your work as a .nmrium.zip archive: your original data files (Bruker, JCAMP-DX, JEOL, etc.) are zipped as-is, and all processing and analysis (phase correction, peak picking, multiplet analysis, integrations, assignments…) is stored alongside as a simple JSON file. Your raw data stays untouched, the archive will still open in 50 years, and the format is FAIR-compliant by design. Read the full format spec.

2. Metabolomics data submission in one command. The new zenodo-nmrium command-line tool lets you submit NMR spectra directly to Zenodo — complete with rich metadata, interactive NMRium visualization, and a structured table of contents — all in a single command. Organize your samples in folders (or as .nmrium.zip files), add an index.yml with your metadata, and run:

   npx zenodo-nmrium ./my-nmr-dataset -t YOUR_TOKEN -p -a

   Your data is published with a DOI, made browsable with NMRium, and fully FAIR-compliant from the start. See the documentation.
