CNGB Nucleotide Sequence Archive (CNSA) is a convenient and fast online submission system for biological research projects, samples, experiments and other information data. Based on the International Nucleotide Sequence Database Collaboration(INSDC) standard and DataCite standard, accepting the submission of global scientific research sequencing data (including raw data and other support data), its data submission service can be used as a supplement to the literature publishing process to support early data sharing. CNSA is committed to the storage and sharing of biological sequencing information and data, and is designed to provide global researchers with the most comprehensive data and information resources, enabling researchers to access and use data easily and deeply.
Raw data and other support data can be submitted to CNSA. Submitting data to CNSA represents that you have acquiesced to the open data protocol. CNSA does not receive relevant data covered by the Human Genetic Resources Regulations.
Raw data refers to all the original data generated by sequencing without any filter theoretically.
You can submit the data that meets the requirements through the project, sample, experiment/sequencing or assembly portal of the homepage. Please follow the page instructions to submit data. Then you will complete the data submission after you upload data files to the FTP server using the FTP account and password given by CNSA or send the data hard disk to CNSA. For all submitted data, not only the data integrity will be checked via MD5, but also the metadata and ethical approvals will be reviewed.
After the raw data and related metadata has been submitted and reviewed by data administrator, CNSA will synchronize these data toNCBI/ENA (European Nucleotide Archive) public database to obtain the NCBI accession ID or ENA accession ID, and automatically return the ID to CNSA in which submitters can view the submitted data information on my submission page.
Other support data except the raw reads, which is related to articles or research, includes but not limited to process and result data, analysis methods, software programs, image files, audio files, video files, imaging files, electronic charts and word documents. CNSA cooperates with Gigascience GigaDB to archive the support data. With a link to DataCite, each dataset will be assigned with a DOI which can be directly referenced.
Please add in the article：The data reported in this study are also available in the CNGB Nucleotide Sequence Archive (CNSA: https://db.cngb.org/cnsa; accession number CNP****).
Please click "Other support data submission" portal on the home page to enter the submission instruction page. Click Excel Excel template file and complete template file, then send it to CNSA data administrator (firstname.lastname@example.org and complete template file, then send it to CNSA data administrator (email@example.com) for review and synchronization to GigaDB.
After other support data has been submitted to CNSA, reviewed by the data administrator, and synchronized to GigaDB, the metadata will be pushed to DataCite who will assign it a DOI which is a standard reference used to publish articles and cited by global researchers. Meanwhile, the dataset will be associated with its raw data's ENA accession ID, which constitutes a collection including raw data and intermediate data to support research and published articles.
CNSA will assign accession ID automatically which is prefixed with CNP (Project), CNS (Sample), CNX (Experiment), CNR (Run) and CNA(Assembly) respectively.
With the full-text search engine on the home page of CNSA, users can search with any combined keywords, obtain the retrieval results quickly, locate and download the related data.
Users can access the CNSA FTP download page through the download button in the navigation bar to download public data. Users can also download data on the Run page or the Assembly page by clicking the accession ID of Run or Assembly which can be acquired through the full-text search engine on the home page. Please comply with the User Instructions.
CNSA does not receive relevant data covered by the Human Genetic Resources Regulations. Please choose other ways to submit such data. Sorry for inconvenience.
Combined with data types and processing methods, CNSA uses the corresponding technologies and management measures to ensure different levels of security.
Submitters can control the data information disclosure by setting up release date in each CNSA data module. The controlled time limits to two years by default. If the controlled time is more than two years, submitters should manually modify the time before it is about to expire. If it is expired, the modification is forbidden and the data will be released automatically.
