From Metagenes

The Annotathon is a dedicated 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 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 language file (currently around 700 terms and sentences); our experience shows that translation by a fluent speaker should take no more than a day (including the student "Rule Book").


The Annotathon concept was imagined by the Marseilles bioinformatics lecturing team:

The open source software is developed by Pascal Hingamp.
