Happy Holidays and New year from the EMDB! Please be advised that the EMDB team will be operating at reduced capacity between December 15th - January 12th. With this in mind we would ask that you be prepared for longer reply times through both our helpdesk system and the OneDep deposition system. well done on a productive 2025, wishing you all the best and we will see you in 2026!
