# GeMS (GNPS Experimental Mass Spectra)

This repository contains datasets used for the [DreaMS project](https://github.com/pluskal-lab/DreaMS):
- GeMS dataset of up to hundreds of millions of unannotated MS/MS spectra mined from the MassIVE GNPS repository.
- DreaMS Atlas - a molecular network of 201 million MS/MS spectra constructed using DreaMS embeddings (built on top of the GeMS-C1 dataset).
- MS/MS spectra labeled with molecular structures used to fine-tune DreaMS (filtered subset of MoNA).
