We aim at creating a friendly and inclusive environment during 3 days of intense work, which should provide the means to create and strengthen collaborations that can be pursued online the rest of the year.

Brainhacks are the opportunity to try new ideas, discover new tools, adopt open science best practices and actively push its boundaries, and to meet the people from all disciplines that are inventing tomorrow’s neuroimaging.

We aim at providing a space where we can all thrive, no matter if it is our first hackathon or if we have never missed one, sharing the best of the support we have received by the open science community during the years. Open science is essential for being able to work together effectively. We want to help build a community where openness is the norm and siloes the exception.

The OHBM hackathon is an independent, official satellite event of the OHBM 2019 Meeting.

Participants are encouraged to post project ideas to our GitHub project page, and to submit a report describing their project to the 2019 Brainhack Proceedings published by F1000 after the event.

Join our projects on the Brainhack channel for updated information on the developing Hackathon content and to contribute your own ideas.

The registration fee is 100 USD and includes onsite breakfast, lunch, and refreshments. Participants are responsible for their own accommodations.

We have an open call for Travel Awards (500 USD and free registration)

Share your project idea in our GitHub repo.

And don't forget to join our Brainhack discussions online either on Slack or Mattermost!

We have been using Slack to meet other participants, discuss projects and people are also getting organised to share accommodations! Slack provides a widespread tool for instant chat and project coordination, and our Slack community currently has 3,000 participants! However, Slack is closed and proprietary, and the free version we use is limited to 10,000 messages. We have already reached this limit, which means that even messages 2 months old are not available anymore.

Because of this, Brainhack is now maintaining a self-hosted instance of the open source tool Mattermost, where we have greater control of our history, keeping all our messages and all our data. We are currently discussing about encouraging the Slack community to migrate to Mattermost. Please read about the pros & cons and share your opinion with us – and if you have been using Slack, give a try to Mattermost – it's the same in blue ; )
