Users FAQ


If you have any further questions please do not hesitate to contact the EGA Helpdesk.



What is the role of the EGA?

The European Genome-phenome Archive (EGA) provides a public and permanent archive for array based, sequencing and phenotype data. The EGA facilitates the secure distribution of archived data, which is subject to controlled access requirements as a result of original consent agreements signed by the individuals whom provided the study samples.


How do I gain access to the datasets in the EGA?

**The EGA does not grant access to datasets and plays no role in data access decisions**

Access is obtained by formal application to the Data Access Committee (DAC) associated with your dataset of interest. Each DAC requires users to sign a Data Access Agreement (DAA), which details the terms and conditions of use for each dataset.

The DAA is specific to each DAC and represents an agreement made between applicant and DAC.

Upon approval, an individual account with the EGA is created and log-in details are sent in a separate email.

An EGA account enables users to make list the datasets you have access to and to download using the EGA download client.

Further information on how to obtain an EGA account can be found here.  


I am a co-applicant. Will I be given a joint access account?

Each applicant is provided with their own exclusive EGA account, together with unique log-in details.

User log-in details are for individual use only and should NEVER be shared, under any circumstances.

**EGA services are only provided to EGA account holders** 


What happens if a co-applicant leaves or a new member needs adding to an existing DAC application?

The appropriate Data Access Committee (DAC) should be contacted to update the application. The EGA will open and close accounts based on the information passed to us from the DACs.


I have changed my place of work since my EGA account was created; can I still have access to data?

You must contact the relevant Data Access Committee (DAC) to update them of any changes.

In order to change user details within the EGA system such as affiliation, changes must be confirmed with the relevant DAC to ensure that data access agreements remain valid.

During the period of re-authorisation, users may not be able to access EGA datasets until appropriate approval has been received from the DAC.


How do I apply to the Data Access Committee (DAC) for the dataset I wish to access?

The current DAC contact details can be browsed here.

A step-by-step guide for obtaining an EGA account can be found here.


I have Data Access Committee (DAC) approval, but I have not received my EGA username and password?

Once the EGA is informed of approved applications by the DAC, an EGA account with the agreed dataset permissions is created.

Users are then sent an email with their log-in details. Please check your email junk/trash folder in case the email has been re-directed.

Please be advised that the EGA can only create or update accounts upon the **direct** instruction of the appropriate DAC.


I have an account with the EGA and would like access to further datasets. What do I need to do?

You need to re-apply to the relevant Data Access Committee (DAC). Once an application has been approved, your account will be updated and an email will be sent to you notifying you of a change made to your account.  The list of DAC's on our system together with contact details can be found here.



How do I download and decrypt the files I have access to?

Your EGA account allows you to identify the datasets you have access to and to download the files associated with each dataset.  

Files may be downloaded using the EGA API, API wrapper or EgaDemoClient, which ever method is choosen the files are encrypted prior to download, using a 'key' or string of characters specified by you the user, before downloading the files to the user specified destination. Files may be transferred using FTP or UDT transfer protocol.  

The EGA download client is also used to decrypt the files once downloaded.


How can I download large datasets as quickly as possible?

Files are downloaded using the EGA API, API wrapper or EgaDemoClient, which enables you to download using FTP or UDT.  The EGA recommends the use of UDT for long distance transfers.

For large datasets, in excess of 20TB, individual download accounts can be created that may be accessed using FTP or Aspera.  Download account generally take 3-5 business days to create, depending on the size of the datasets required.

In exceptional circumstances, encrypted data can be transferred to a user supplied hard drive, which should be sent to:

Mr Jeff Almeida-King
The European Genotype Archive,
European Bioinformatics Institute
Wellcome Trust Genome Campus
Cambridge CB10 1SD

**The turnaround time for transferring data (upto 10Tb) to drives is 90 days**

To ensure that no custom charges are applied, please describe the goods as 'Intellectual  Property Rights - no commercial value'.
We reserve the right to refuse delivery or seek re-imbursement of costs if this instruction is not followed.

For all hard drive request please contact and let us know the permitted datasets you would like to have transferred.



I have forgotten or misplaced my user account password; how do I get a new one?

Click on 'Request a new password' located at the bottom of the User Login box to the right of the EGA homepage, then type in your registered 'email address' and a one time link will be sent to your registered email address to reset your password.  Once your password requests has been authorised (please allow 3-5 days), you will receive email confirmation that your password has been changed and account is ready to use again.


Why is my account not active or is 'blocked'?

Accounts are inactivated/blocked automatically when passwords are in the process of being validated by an EGA administrator.  Passwords are validated in response to a request made by a user to change their password or when the user logs into their EGA account for the very first time.

Password verification is a very important security step, which cannot be bypassed.  Passwords are usually verified within 24 business hours and an email is sent to an account holders registered email address when the account is active/unblocked.  

In exceptional cicumstances accounts may also be blocked if the account has been subject to misuse, for example, if the account is being accessed by anyone other than the account holder. 

Please only contact if your account has been blocked for longer than 24 hours.
