Register a Study Interactively

To submit data into ENA you must first register a study to contain and manage it. Studies (also referred to as projects) can be registered through the Webin Portal. Log in with your Webin credentials and select the ‘Register Study’ button to bring up the below interface:


Fill out the form to describe your study: most of these values can be edited later if needed. This study will eventually be the entry point into your data, so provide a sufficiently detailed abstract that users can get a good overview of your work. If you will be submitting a genome assembly which includes functional annotation please see the Locus Tag Prefixes section below.

The release date can be as much as 2 years beyond the present date, and on this day the study and its data will automatically be made public. Notification of this will be sent in advance to all email addresses registered with your submission account. You can change the release date at any time to make it sooner or later, but once the data becomes public you may not make it private again. Read more about data publication in our Data Release Policies FAQ.

Once registration is complete, you will be assigned accession numbers. You may return to the dashboard and select the ‘Studies Report’ button to review registered studies.

Locus Tag Prefixes

If you intend to submit a genome assembly which includes functional annotation, you will need to register a locus tag prefix. To do this, first check the box asking ‘Will you provide functional genome annotation?’

An additional field will appear at the bottom of the page allowing you to add one or more locus tag prefixes. All prefixes you enter must conform to the following rules:

  • Starts with a letter
  • Between 3 and 12 characters long
  • Is upper case
  • Contains only alpha-numeric characters and no symbols such as -_*

Note that the prefixes will only be validated when you click the ‘Submit’ button. Once you complete registration of a locus tag prefix, it will take 24 hours for the prefix to be usable.
