Helps to resolve Universal Spectrum Identifiers (USI) for metabolomics data (e.g. GNPS Spectral Libraries, GNPS Molecular Networking Spectra, MS2LDA Motifs, Massbank Spectra, MassIVE public spectra).
These identifiers are based on draft USI and draft Metabolomics USI identifiers.
Thus, they are subject to change, and so for the moment, they will be specified as mzdraft instead of mzspec in the first block.
Thank you for your patience and working with us!
