NeuroDataReHack 2026

NeuroDataReHack 2026

July 12, 2026 - July 17, 2026

HHMI Janelia Research Campus, Ashburn, VA

Hackathon

Summary

Unlock new discoveries in neurophysiology through secondary analysis.

Objective

The DANDI Archive now has 450+ neurophysiology datasets in the Neurodata Without Borders format spanning many species, brain areas, task types, and imaging modalities. These include high-value datasets, e.g. from Allen Institute OpenScope, the MICrONS project, and the International Brain Laboratory Brain Wide Map, as well as diverse contributions from neuroscience labs around the world. In this workshop, we will teach attendees about the open neurophysiology datasets available on the DANDI Archive and train them on how to maximally utilize the archive and the NWB standard to incorporate existing data into their scientific workflows. Feedback from attendees will be used to improve the software and data standard to better enable reanalysis workflows.

Example projects include but are not limited to:

  • Determine whether your result is present in another species or brain area.
  • Showcase the capabilities of your tool or analysis on existing data from another lab.
  • Explore follow-up questions to a study.
  • Create educational content that uses open data.

This event will primarily focus on analyzing existing data in NWB and on DANDI, not converting data to NWB. If you are interested in learning how to convert data, consider signing up for an NWB Data Conversion Workshop.

Application

Applications for NeuroDataReHack 2026 are now closed, and the event took place July 12 to 17, 2026. The recorded talks are available on the NeuroDataReHack 2026 playlist, and the full schedule with links to each recording is below. To hear about future NeuroDataReHack events, subscribe to our mailing list.

Schedule

The full schedule is below. Talks are linked to their recordings; the NeuroDataReHack 2026 playlist collects all of them. Participants checked in on Sunday, July 12, and most of each day was devoted to working on projects, with meals and breaks provided.

* Recordings for the talks marked with an asterisk are not yet available online. Some were given remotely and the room recording did not capture the presenter’s shared slides. We are following up to add them where recordings can be recovered.

Eligibility

Eligibility is broad. This course is intended for PhD students, postdoctoral researchers, principal investigators, or similar. Advanced undergraduates may be considered on a case-by-case basis. We welcome applicants from all areas of neuroscience, including but not limited to experimentalists, computational neuroscientists, and data scientists. Applicants should have basic programming experience in Python or MATLAB and experience with neurophysiology research. Preference will be given to applicants who have a specific project in mind that involves reanalyzing existing neurophysiology data in NWB format and who has not previously attended a NeuroDataReHack event.

Logistics

Thanks to the generous sponsorship of The Janelia Research Campus, this event will be free to participants:

  • There is no registration or application fee.
  • Participants will be provided a private room at Janelia Research Campus for the duration of this event, checking in on Sunday, July 12, and checking out the evening of Friday, July 17 or the morning of Saturday, July 18.
  • Breakfast, lunch, dinner, and coffee breaks will be provided. Janelia is adept at accommodating dietary restrictions; please indicate any dietary restrictions on your application.
  • You will be responsible for booking your own flight and transportation to Janelia Research Campus.
  • You will be responsible for determining visa and/or healthcare requirements for travel to the United States. Please plan accordingly, as this process can take several months. We would be happy to provide a letter of invitation to support your visa application if needed.
