The European Genome-phenome Archive Accessing and submitting controlled access data Jeff Almeida-King User Support & Outreach
EGA Session summary • Introduction to the EGA • Accessing data (+hands on) • Submitting sequence (+hands on)
EBI: Open and Controlled access archives Structural variants Phenotypes Sequence Variants EVA Open & public archives Controlled access archive
What is EGA controlled access data anyway? • Usually human, personally identifiable (Genetic, phenotypic) • Affiliated to medical research or consortium projects • Requires secure storage and distribution • Access determined by formal application procedure • Informed consents specifying controlled release requirements
EGA Overview • Launched 14th July 2008 • 2500+ data access accounts; 125+ submission accounts • 700Tb+ data archived (200,000 samples); 600 datasets in distribution • Data access decisions made by a Data Access Committee (DAC)
Using Your EGA Account • Distribution requires data preparation • Download accounts require manual set-ups • Download accounts expire in 14 days • Data must be decrypted using keys supplied offline

Exercises: Accessing data (Hands-on) www.ebi.ac.uk/ega/tutorials/accessing_data • Navigating to your study of interest • Using your EGA acount • Downloading data • Directory: [Shared_folder]/ESGI/EGA/downloading_data/<token_name> (exercise 3)
Why Submit to the EGA? Funders and journals increasingly require researchers to have a data sharing plan. 1) Wellcome Trust "Policy on data management and sharing” http://www.wellcome.ac.uk/About-us/Policy/Policy-and-position-statements/WTX035043.html 2) Nature "Availability of data and materials” http://www.nature.com/authors/editorial_policies/availability.html 3) Public Library of Science (PloS) "Sharing of Materials, Methods, and Data”http://www.plosone.org/static/policies.action#sharing
Additional requirements for an EGA submission • Submission statements & DAC access policy • File preparation: Data encryption • Register DAC, Policy and Dataset
