Since 2007, we have removed E-mail addresses and phone numbers from sequence data.
If you can find a related paper at REFERENCE on DDBJ flat file, contact information would be available on the paper.
When you wishes to contact to the submitter(s) of an entry of your interest, please contact us via Inquiry to the sequence submitters (submitted to DDBJ) with reasons briefly, then we will forward your message to the submitter(s).
In general, see the rule of the journal (i.e. Instructions to Authors), and follow it.
At INSDC, we recommend you to describe accession numbers in the footnote on the title page of your paper as following;
Note: Nucleotide sequence data reported are available in the DDBJ/EMBL/GenBank databases under the accession number(s)----'.
It indicates that this data is directly submitted from the submitter. The term is the antonym to "journal scan".
REFERENCE 1 is the information of submitter(s), not general reference.
So, do not describe "Direct Submission" in the title for literature in REFERENCE 2 or after.
There are some possibilities as followings.
In case of 3) or 4), we will check and support it.
Please contact us from contact form by selecting the item, "Updating Submitted Data" with accession numbers, or by mail to.
For once published entries, we can restrict to use the data, if the conditions are right.
In case of the restriction, DDBJ will not include the data in its periodical release and remove from all services under DDBJ.
However, the data is permanently available on getentry queried with its accession number.
# The rule is not applied, when the data is published by any mistake of INSD.
This policy is written in the document prepared by International Advisory Committee of INSD on Overview of International Nucleotide Sequence Databases Policies as follows;
All database records submitted to the INSD will remain an entry accessible as part of the scientific record. Corrections of errors and update of the records by authors are welcome and erroneous records may be removed from the next database release, but all will remain permanently accessible by accession number.
In addition, there are a number of databases constructed by occasionally using data from INSD.
DDBJ can not support to delete data from such databases. If you are to delete the cited data on other databases, you have to contact managing staff of each database, directly.
Please confirm if the ID on the paper is Accession Number Assigned by INSD or not.
If accession numbers on the paper, please contact us from contact form by selecting the item, "Updating Submitted Data" with following items.
It is getentry.
"getentry" is a system for data retrieval by accession numbers, etc.
In general, the sequence data will be available on getentry from the day after processed to release.
DDBJ is functioning as one of the international nucleotide sequence databases, including EMBL-Bank/EBI in Europe and GenBank/NCBI in the USA as the two other members.
When DDBJ releases the submitted data, EMBL-Bank and GenBank will load the data into their own services, respectively.
See Sequence Data Transition.
Note that the data are converted into EMBL-Bank or GenBank format.
In general, the data released from EMBL-Bank or GenBank are loaded into DDBJ services and published from DDBJ within their released date.
The data released from DDBJ are loaded into ENA/EBI and GenBank and published from them within a few days.
However, the data release processes at all three databases may be delayed, because of system maintenance, troubles on the network, or any other reasons. So, we can not specify the temporal differences among them.
The rule to translate nucleotide sequence into amino acid sequence is specified in accordance with agreements of International Nucleotide Sequence Database Collaboration.
The codon table using a CDS feature is specified in the value of /transl_table qualifier as a number of The Genetic Codes.
There are three points frequently misunderstood.
INSD; International Nucleotide Sequence Database are composed of DDBJ, ENA and NCBI, and collect experimentally determined nucleotide sequence data.
A unique accession number issued by INSD for each submitted sequence data is defined as the INSD accession number.
On DDBJ flat file, the accession number is described in ACCESSION line.
If multiple entries are united to an entry, or if an entry is extensively modified after the submission, the responsible data banks may assign a new accession number to it. In these cases, the new accession number is called the primary accession number, and the old accession number(s) is/are called the secondary accession number(s).
In the flat file, the primary accession number is indicated first, then the secondary accession number(s) follows.
You can find the same updated entry with both the primary and the secondary accession numbers, in general.
However, if the old entry with secondary accession number has previously been open to the public, the old one is not removed. So, you can find the old record by getentry.
To get a FASTA format of TSA or WGS entries, please use "getentry", specifying the following values.
ID : Specify the Accession Number.
Output format : Select "total nt seq FASTA" for the result.
Result : Select one from the following filetype for the output.
For more information about each value, please see getenry HELP.
