While our core software remains completely open-source and free for the world, the Garyfallidis Research Group provides structured premium partnerships for academic labs and corporate teams requiring enterprise-grade optimization, sequence validation, and clinical trial compliance.
The Global Ecosystem Behind GRG
GRG is the headquarters and scientific lead of DIPY — but DIPY is an international project. Partnering with GRG means partnering with the core of a worldwide open-source community.
GRG Headquarters
DIPY — Diffusion Imaging in Python
The world's largest open-source library for diffusion MRI analysis. Originally founded by Prof. Garyfallidis at the University of Cambridge, DIPY is today maintained by an international team spanning five continents. GRG remains the scientific lead and primary development hub — giving our partners direct access to the people who design the algorithms, not just the documentation.
Annual DIPY Workshop
Every year GRG organizes the DIPY Workshop — a hands-on, internationally attended training event that brings together neuroimaging researchers, engineers, and clinicians to learn the latest methods in diffusion MRI analysis directly from the core developers.
DIPY Workshop 2026 →FURY & THETAN
Beyond DIPY, GRG leads FURY — a high-performance 3D scientific visualization framework — and THETAN, a next-generation machine learning framework targeting state-of-the-art performance across neuroimaging and signal processing domains (release planned Fall 2026).
Why Partner with GRG?
Bridging cutting-edge computational neuroengineering and real-world industrial applications, GRG partnerships give your team a decisive advantage.
Eliminate Engineering Bottlenecks
Direct access to core maintainers of DIPY, FURY, and THETAN to optimize processing pipelines, configuration tuning, and throughput — eliminating the months your team would otherwise spend reverse-engineering undocumented internals.
Sequence Validation
Expert consulting on optimal diffusion acquisition strategies — multishell b-value schemes, directional resolution for crossing fibers, and protocol harmonization across scanner platforms — grounded in two decades of hands-on MRI research.
Regulatory & Compliance Support
Algorithmic documentation, validation datasets, and reproducibility evidence essential for FDA submissions and clinical trial compliance. Leverage an R1 university research group's institutional credibility for your regulatory pathway.
Premium Partnership Tiers
All tiers include access to our open-source ecosystems — premium layers add direct human expertise. Not sure which fits? Ask us.

Frequently Asked Questions
Yes. You can upgrade to a higher tier at any point during the year — we pro-rate the difference and apply it immediately. Downgrades take effect at the next annual renewal date.
All billing runs through Indiana University's official merchant accounts. We support ACH / Wire Transfer and Purchase Orders (POs) — the same mechanisms Fortune 500 procurement teams use for university contracts. We provide a formal IU invoice with all required vendor information. Contact us for a W-9 or vendor setup forms.
Additional consultation blocks are available for purchase at an hourly rate reserved for active partners. We will notify you before you exhaust your allotment so there are no surprises. Contact us to discuss your typical usage and we can recommend the right tier from the start.
DIPY, FURY, and our other software will always remain free and open-source under permissive licenses. A partnership tier purchases direct human access — the time of the core developers who build the software — along with SLA commitments, private communication channels, and tailored deliverables that the open-source community model cannot provide at scale.
Absolutely. DIPY itself is an international project with contributors and users across five continents. GRG operates as a globally collaborative group and routinely works with labs and companies outside the United States. IU handles international wire transfers and can provide the necessary documentation for foreign procurement processes.
The DIPY Workshop is an annual, internationally attended training event organized by GRG where participants learn the latest diffusion MRI methods directly from core developers. Workshop registration is open to all — contact us for partner pricing and priority access.
