Dear colleagues, The Neurodata Without Borders (NWB) <http://nwb.org/> team is organizing two upcoming events: NeuroDataReHack and the Open Neurodata Showcase. NeuroDataReHack 2024 July 8-12, 2024 Janelia Research Campus, Ashburn, Virginia, USA The goal of NeuroDataReHack is to train participants to generate new insights from existing neurophysiology data through secondary analysis. The DANDI Archive <http://dandiarchive.org/> now has 200+ neurophysiology datasets in the Neurodata Without Borders <http://nwb.org/> format spanning many species, brain areas, task types, and imaging modalities. These include large-scale datasets from the Allen Institute, the MICrONS project, and the International Brain Laboratory, as well as diverse contributions from neuroscience labs around the world. NeuroDataReHack will teach attendees how to maximally utilize the data and computational resources of the DANDI Archive to incorporate existing data into their scientific workflows. Example projects include but are not limited to: - Determine whether your scientific findings are present in another species or brain area. - Guide the generation of hypotheses for a new project or grant application. - Showcase the capabilities of your tool or analysis on published data from another lab. - Explore follow-up questions to a study that has published data. The workshop is free to attend, and on-site housing and meals will be provided. Travel support is limited. Learn more and apply at the NeuroDataReHack 2024 website <https://neurodatawithoutborders.github.io/nwb_hackathons/HCK21_2024_Janelia_NDRH/>. The deadline to apply is March 10. *Open Neurodata Showcase* July 2, 2024, 9-10:30 AM PDT Virtual In the week before NeuroDataReHack, the NWB team is organizing a virtual poster session on the Gather platform to bring together data contributors and anyone interested in reusing existing neurophysiology data. This virtual event offers a unique opportunity for participants to explore and engage in discussions about particular dandisets, and allows data contributors to showcase their projects. Anyone interested in using open neurophysiology datasets or presenting on their published neurophysiology datasets is welcome to attend. Learn more and register at the event website <https://neurodatawithoutborders.github.io/nwb_hackathons/HCK20_2024_OpenNeurodataShowcase/> .
