The Assemblathon is a collaborative, recurring effort to spur improvements in computational methods for genome assembly. Teams use their own software to assemble one or more genomes that the organizers of the Assemblathon make available (see the rules for more details). All participants have the same amount of time to try to assemble the genomes, and then the organizers evaluate each group’s efforts.

Two rounds of the Assemblathon have been conducted to date, and  Assemblathon 3 is in the early planning stages (contact Ian Korf email | website).
