- Feature Table Definition(FT-Doc) is the common annotation manual among the three banks(DDBJ, EMBL-Bank, GenBank) for the construction of the DDBJ/EMBL/GenBank International Nucleotide Sequence Database. Following the decision at an International Collaborators Meeting(ICM) held annually in May, this FT-Doc is updated every year. In December 2009, FT-Doc is updated, based on the 22nd International Collaborators Meeting.
