A total of 2,540 respondants took the time to fill in this EMBL-EBI survey. We will learn how EMDB and other services like EMPIAR and PDB help you and this will help EMBL-EBI make the case for why open data resources are critical to life science research. Thank you for the incredible number of responses.
