The EMBL-EBI webinar series features live sessions lasting between 30 minutes and 1 hour. These webinars give a brief introduction to a single data resource or a group of data resources, and in some cases cover new features in detail. These live presentations are followed by a question and answer session. Webinars are recorded and made available online through the free online training offerings. Train online provides freely accessible online tutorials across the range of EMBL-EBI resources whilst also providing courses to deliver background concepts in a range of bimolecular topics.
