Data source

Assembly database comprises assembly data from CNSA and external web source NCBI Assembly. CNGBdb acquires assembly data from NCBI Assembly 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 experiment record (e.g. includes the original source ID which can be clicked to the NCBI Assembly 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
