Bioinformatics techies in Europe! ELIXIR invites you to participate in the BioHackathon Europe 2020. The event is open to participants from both ELIXIR and non-ELIXIR countries and organizations. You'll get to collaborate with your peers to gather, discuss, and implement ideas/projects during intensive and productive coding sessions. The topics will be aligned to challenges proposed by ELIXIR platforms (data, tools, compute, interoperability and training), ELIXIR communities (Human Data, Rare Diseases, Marine Metagenomics, Plant Science, Metabolomics and Proteomics), a selection of new tools and communities (e.g., Cytoscape and reproducible networks) proposed by ELIXIR France, and a set of common challenges proposed by the sister BioHackathon organised in Japan.
