What to bring?


The Neurodata Without Borders project (NWB, nwb.org) is an effort to standardize the description and storage of neurophysiology data and metadata. NWB enables data sharing and reuse and reduces the energy-barrier to applying data analytics both within and across labs. Several laboratories, including the Allen Institute for Brain Science, have wholeheartedly adopted NWB. The community needs to join forces to achieve data standardization in neurophysiology. The purpose of the hackathon is to bring the experimental neurophysiology community together to further adoption and the development of NWB, the NWB software libraries, and the progress of the scientific workflows that rely on NWB. Members of the community will exchange ideas and best practices for using NWB and the libraries, share NWB based tools, surface common needs, solve bugs, make feature requests, brainstorm about future funding and collaboration, and make progress on current blockages. The event will also enable NWB developers and users to interact with each other to facilitate communication, gather requirements, and train users.

Note: This event is meant to foster community and collaboration around NWB, not competition. As such, this is really more of a “workshop” or “tutorial” than a “hackathon.” There will be no judges nor prizes. Participants will be expected to bring data from their own lab and/or collaborate with others to build integration with NWB.
