DDBJ has accepted nucleotide sequence data submissions by SAKURA, MSS(Mass Submission System), or 'Sequin'. However, DDBJ will terminate accepting submission by 'Sequin' as of the end of January, 2011. Alternatively, by using SAKURA or MSS, you can submit your data easily and quickly by far. Please use SAKURA or MSS hereafter.
Please use SAKURA or Mass Submission System (MSS) for your future submission to DDBJ. Reference: Workflow of the data submission to DDBJ
(B) Mass Submission System (MSS) If you need 'Sequin' submission by unavoidable reason, please send your data to GenBank.
Thank you very much for your understanding and cooperation.
