How to cite data in ENA

All accessions issued by ENA, along with all accessions issued by its international partner institutions under INSDC, can be viewed in the ENA browser by pasting the accession into the Text search box or through the following URL: http://www.ebi.ac.uk/ena/data/view/<accession>

e.g. http://www.ebi.ac.uk/ena/data/view/BN000065

Numeric ranges for accessions with the same prefix are also supported via http://www.ebi.ac.uk/ena/data/view/<accession1>-<accession2>
e.g. http://www.ebi.ac.uk/ena/data/view/BN000066-BN000070

Extensive advanced options to render and retrieve ENA data are described here.


Accession numbers take the following formats, where $ is any large case alphabetical character and # is any numeric character.

Format Record type
$##### sequence
$$###### sequence
$$$##### coding
$$$$######## contig
PRJ$$####### study
$RS###### sample
SAM$$###### sample
$RP###### study
$RX###### experiment
$RR###### run

The recommendation for citing collections of data is to be concise where possible but precise. Concise citations use higher-level accessions that may be available to define a set of records. For example, in a single organism genome assembly, a study accession will have been issued. This should be used to cite the assembly. In cases where more than one organism has an assembly as part of the same project, the project will point to data underlying more than one assembly, so the need to cite a single assembly from the set would not be met using a citation of the study record. In this case, the contig range and/or scaffold and chromosome accessions (as available) should be cited for precision.

The following tracking identifiers are issued around submission, where # is any numeric character. These should not be cited publicly to refer to data as they have no permanent meaning beyond a submission transaction:

Format Submission transaction
Hx########## Webin session
[E,S,D]RA###### submission package
