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.
Counts reflect available QC tables, not the 2025 paper's fixed snapshot.
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.
