INDI Retrospective Studies

Curated, ready-to-use subsets of INDI (International Neuroimaging Data-sharing Initiative) retrospective releases, prepared for the Pittsburgh Fiber Data Hub. This repository consolidates links, essential metadata, licensing, and selected derived artifacts (e.g., QC tables, tractography-ready files) to streamline reuse and replication.

Access note: Many datasets are hosted on external portals or S3 (e.g., NITRC, fcp-indi). Always review each dataset’s license and acknowledgments before use.

What’s included

For each dataset mirrored under data-indi/retro, this repository provides:

All raw imaging data remain hosted by INDI / project owners and are subject to each dataset’s data use terms.

SIMON — Single Individual Volunteer (73 sessions, multi-site)

Dataset: SIMON — Single Individual Volunteer for Multiple Observations across Networks Design: Longitudinal single healthy ambidextrous male (age 29–46) scanned in 73 sessions across multiple sites and scanner models, including partial acquisition under the Canadian Dementia Imaging Protocol (CDIP). New sessions continue to be added.

MPI-Leipzig Mind-Brain-Body (LEMON & N&C)

Dataset: MPI-Leipzig Mind-Brain-Body (LEMON + Neuroanatomy & Connectivity) Participants: 318 total

Data are organized into two protocols:

LEMON (ses-01) — Structural & qT1 focus

Neuroanatomy & Connectivity (N&C, ses-02) — Resting-state focus

Deep phenotyping & physiology

Complete imaging subset: 45 participants have full LEMON+N&C multimodal data (qT1, T2, 3D FLAIR, DWI, SWI/QSM, 75 min rs-fMRI, field maps).
