The deadline for submitting entries to the Challenge held by conference on Informatics for Phylogenetics, Evolution, and Biodiversity (iEvoBio) has been extended by one week to June 20, 2011.

The iEvoBio Challenge is a competition to create a new software tool, or add a new feature or features to an existing platform. Entries to the Challenge need to respond to its theme, which for 2011 is "Data Integration".

Further information on the nature of challenge entries and how to submit them can be found on the iEvoBio website at http://ievobio.org/challenge.html . Selected candidates will make short oral presentations to demonstrate their work in a "Challenge session" at the conference, and if suitable will automatically be entered into the Software Bazaar track of the conference. The winning entries will be selected by a vote of the iEvoBio meeting participants, and will be awarded cash prizes.

Challenge entries are only 1 of 5 kinds of contributed content that iEvoBio will feature. The other 4 are: 1) Full talks (closed), 2) Lightning talks, 3) Software Bazaar entries, and 4) Birds-of-a-Feather gatherings. All tracks except Full Talks remain open(see http://ievobio.org/ocs/index.php/ievobio/2011/) .

More details about the program and guidelines for contributing content are available at http://ievobio.org.
