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
|Silver|| Isolated or lysate/crude, Published data showing presence of molecule in the sample, Requires attendance of a GNPS curator training workshop
|Bronze|| Any other putative, complete or partial annotation
|Challenge||Unknown Identity, open to community to help annotate.||10|
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 email@example.com.
