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 800,000 peaks from 3,500 MSTs by GC-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. To expand the dataset by using another type of
MS instruments (e.g. LC-MS, CE-MS) are planned in near future. MassBase developed at Kazusa DNA
research institute and supported by the NEDO project.
