The spectral libraries are categorized based upon quality of the data. The level indicates both the quality of the MS/MS spectra as well as the trust worthiness of the annotations. These reflect both quality of the MS/MS spectra as well as the trust worthiness of the annotations.

There are three levels: 

Quality Level Description Quality Number
Gold Synthetic, Complete structural characterization with NMR, crystallography or other standard methods as defined in the publication guidelines for Journal of Natural Products, Privileged users
1
Silver Isolated or lysate/crude, Published data showing presence of molecule in the sample, Requires attendance of a GNPS curator training workshop
2
Bronze Any other putative, complete or partial annotation
3

By default, users will have access to Bronze, but approval is required to contribute to silver and gold libraries. To obtain training and access please email Mingxun Wang at miw023@ucsd.edu.
