Data source

Sequence database comprises sequence data from CNSA and external web sources, including NCBI Refseq, Genbank, WGS, TSA. CNGBdb acquires sequence data from these public databases via FTP. All data obtained from FTP are parsed and integrated according to certain meta-information structure, and displayed on the page in order to provide search, retrieval and download services for users. Every sequence record (e.g. includes the original source ID which can be clicked to the NCBI Refseq details page.

CNGBdb complies with the data usage agreement and related requirements of these source databases. If you have any question about the above methods of data references or think that the data references are not reasonable, please contact
