MassIVE is an online repository for publicly available datasets. MassIVE provides a location for researchers to access datasets that have been made available by others, oftentimes alongside publication. The datasets available remain alive long after publication. At GNPS, users will be able to browse datasets, download datasets, and comment on datasets. These comments can be accompanied with new data or new analysis that enriches the MassIVE dataset. Additionally, users can subscribe to specific datasets. While the underlying data may not change, the analysis and understanding of the data will continue to improve. To enhance the analysis, datasets submitted to MassIVE through GNPS will be periodically searched against the ever growing annotated spectral libraries and new putative identifications within those datasets are reported to subscribers. Beyond new identifications within a dataset, subscribers will also be made aware of other datasets that exhibit chemical similarities to the subscribed dataset. This allows for users to be connected via their research interest to similar datasets.
Here we will describe how to upload data into MassIVE specifically for GNPS.
For more detailed information about general MassIVE dataset submission see here .
MassIVE datasets are composed of data files. Acceptable input files are as follows:
|Bruker||mzXML||Centroided MS1 and MS2|
|AB Sciex||WIFF, mzXML|
NOTE: We do not support file archives of data files (e.g. zip, tar). Data files must be submitted as the naked file and not in an archive.
The preferred method to upload data is through FTP. The ftp server is at massive.ucsd.edu and please refer to documentation here .
At the GNPS splash screen, users can click this icon
to create a MassIVE dataset.
Login with your GNPS login and hit Submit Data.
Further instructions can be found here.
The title is the display that users will use primarily to filter datasets. For GNPS datasets, a specific title format is required.
The GNPS prefix is required for GNPS datasets. If this is not provided GNPS MassIVE datasets are not shown to GNPS users.

FTP connections to massive.ucsd.edu might fail on new accounts. To work around this bug, please go to massive.ucsd.edu/ProteoSAFe and click Select Input Files. This will bring a popup, now try to again connect via FTP, if the problem persists, please email firstname.lastname@example.org.
