The concept of metabolomics is emerged as a new omics layer of system biology in this several years,
but a flood of publicly available data for bioinformatics research is not observed yet. MassBase is
an archive of a huge amount of mass spectrum tags (MST) include both known and unknown assigned (or
predicted) peaks which are found in biological samples (mainly from plants) and standard chemical
reagents for peak annotation. The aim of the database is to enhance the bioinformatics research of
metabolomics using a huge metabolomics dataset. Over 1,700,000 peaks from 5,132 MSTs by GC-TOF-MS
and 174 MSTs by UPLC-TOF-MS are archived as text format files with its binary raw data files.
Scanned mass spectra (SMS), a text format list of mass signals in all scans of a binary raw data are
also archived. It should help to verify a computational peak assignment and to study an improvement
of a quality of peak assignment. All dataset is freely downloadable from this site. Over 30,000 mass
spectrometry data (binary files produced from mass spectrometers) are currently under processing for
MassBase registration as the text-formatted files through our computational pipeline. MassBase
developed at Kazusa DNA research institute and supported by the NEDO project.
