30,000+ fiber datasets, ready to track.
Processed diffusion MRI from OpenNeuro, INDI, HCP, TCIA and more, shared as compact fiber data, 50–100× smaller than raw DWI. Download with a browser, the command line, Python, or directly in DSI Studio.

About the Hub
The Fiber Data Hub shares processed fiber data derived from diffusion MRI: fiber orientations, anisotropy, diffusivities and other metrics needed for tractography, without redistributing raw DWI.
These derivatives are typically 50–100× smaller than the original scans, so large public datasets can be searched, quality-checked and analyzed without repeating preprocessing.
