NWB Workshops and Hackathons

Welcome to the NWB & DANDI Tutorial at COSYNE 2024!

The Neurodata Without Borders (NWB) team is holding a tutorial on the NWB data standard and DANDI Archive during the tutorial session of COSYNE 2024.

The NWB project 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 analyzing data both within and across labs. NWB is more than just a file format; it defines an ecosystem of tools, methods, and standards for storing, sharing, and analyzing neurophysiology data, including extracellular electrophysiology, intracellular electrophysiology, optical physiology, and behavior.

The DANDI Archive now has 175+ publicly available neurophysiology datasets stored using the NWB data standard, including from the Allen Institute, International Brain Laboratory, MICRONS project, and over 100 individual labs.

At this tutorial, we will teach you how to:

Bring your laptop to work along with the demonstration. To get familiar with NWB and DANDI prior to attending, please refer to this documentation.


There is NO additional fee to attend. When registering for the main meeting, select the “Neurodata Without Borders Data Standard and DANDI Archive for Neurophysiology Data Tutorial”.
