The Data Analysis
portal will allow you to organize and visualize your mass spectrometry data. Leveraging the molecular networking techniques, there are additional tools to aid in understanding the unknowns in your sample.
Check out the documentation
and live demo
Further, a separate dereplication workflow
is provided as a standalone workflow.
Create Public MassIVE Datasets
your own data to be made public MassIVE datasets. These MassIVE datasets must be prefixed with GNPS
to be visible to other GNPS users. Take advantage of continuous identification
to learn more about your dataset after publication automatically. New hits to the community curated libraries and related datasets are reported. Documentation
Contribute to Libraries
Be a part of the collaborative community effort to create
the definitive collection of natural products MS/MS spectra.
Additionally users can contribute varying levels of quality of spectra: bronze
GNPS gives the power to add spectra, update annotations, and facilitate dialog around these spectra, to provide a truly collaborative and open natural product MS/MS database.
For documentation and definition of quality requirements click here
To make corrections to and comments on exisiting spectra in the libraries, users should refer to this documentation
MassIVE Public GNPS Datasets
publically available datasets. Here you can download these datasets as well as comment on them so others in the community can see any updates or any new analysis.
Additionally, users can subscribe to the datasets and get updates when new identifications are made via GNPS's continuous identification
To read further on how to take advantage of the subscriptions to MassIVE datasets and other social networking features click here
Browse Community Spectral Library
the community contributed and community curated spectral libraries of natural products. These MS/MS libraries are community contributed and community curated. Users can peak at the inside of these libraries, as well as use them for data analysis. If corrections need to be made, users should refer to this documentation
Bridge the connection between molecules and datasets. Explore
exactly where certain molecules are found in all the publically available dataset at GNPS. Powered by GNPS's continuous identification
, users are able to see not only which datasets contain what compound, but how many known and unknown analogs exist in all datasets!
Rarefaction Curve Generation
The Data Analysis
portal will additionally provide a method to create rarefaction curves. These curves will allow you to assess the diversity of MS/MS spectra and ultimately of compounds within your data. For documentation click here
There will always be spectra that stumps the best. Scientists can share these intriguing unidentified yet interesting spectra as challenge spectra.
