Remarks
As of January 2010, 16 research groups, 12 in Japan, 3 in the United States and 1 in Germany, are contributing data to MassBank (Table 2). Mass spectral data, chemical compounds and analytical methods are summarized for each research group. These data are distributed on eight MassBank data servers, one of which is located in the Leibniz Institute of Plant Biochemistry (Halle, Germany). Eight small research groups currently without their own data servers contribute their data to the MassBank data servers in Japan or Germany.
