The Annotathon is a dedicted online bioinformatics training environment. Trainees are invited to annotate metagenomic DNA fragments added to their personnal sequence cart from various oceanic locations (Global Ocean Sampling project by Venter et al.). The analyses include the detection of potential coding regions, the search for sequence homologs and identification of conserved protein domains, as well as the reconstruction of phygenetic trees.

The Annotathon is designed to manage large trainee cohorts grouped into teams (such as students following the same course) supervised by instructors. Each sequence annotation produced by trainees is examined, commented on and evaluated by instructors twice. This allows trainees to revise their initial annotations, thus improving their bioinformatics skills. After the team closing date, trainee evaluations are compiled into an overall grade.

The Annotathon concept was imagined by the bioinformatics lecturing team of the Luminy Sciences Faculty (Université de la Méditerranée, Marseille, France): Pascal Hingamp, Céline Brochier, Emmanuel Talla, Daniel Gautheret (now at U. Orsay), Denis Thieffry & Carl Herrmann. The open source software is developed by Pascal Hingamp.


The Annotathon is currently available in english & french. Offers to translate the interface in further languages are warmly welcomed! All language specific terms are externalized in a single language file (currently around 500 terms and sentences); our experience shows that translation by a fluent speaker should take no more than a day (including the "Rule Book").
