Data source

Experiment database comprises experiment data from CNSA and external web source NCBI SRA. CNGBdb acquires experiment data from NCBI SRA 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. https://db.cngb.org/search/experiment/SRX952210/) includes the original source ID which can be clicked to the NCBI SRA 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 CNGBdb@cngb.org.
