Add 16 missing datasets: Asian cohorts, traveling-subjects, ultra-high-field, global coverage

[kondratevakate]

Adds 16 datasets that were missing from the list, primarily addressing gaps in Asian coverage, recent traveling-subjects resources, ultra-high-field references, and global representation.

New entries

Asian cohorts (previously absent)

• SRPBS Traveling Subject MRI (Japan, ATR) — 9 subjects x 12 scanners x 143 sessions; Asia primary harmonization resource
• SRPBS Multi-disorder MRI (Japan, ATR) — 993 patients + 1421 HC, MDD/SCZ/ASD/OCD, 12 sites
• J-ADNI (Japan, NBDC) — 537 subjects, ADNI protocol, longitudinal T1+PET+CSF
• KBASE (Korea, SNU) — Korean ADNI, ~500 CN/MCI/AD, longitudinal
• CHIMGEN (China, 33 sites) — 7000+ subjects, imaging genetics, largest Chinese neuroimaging genetics cohort
• CCNP / devCCNP (China, BNU+CAS) — 1520 target, lifespan 6-90 yr, accelerated longitudinal with 3 waves
• SLIM (China, Chongqing) — ~600 university students, 3 longitudinal timepoints

Traveling-subjects / multi-site (2025 additions)

• ON-Harmony 2025 — 20 subjects x 6 scanners x 3 vendors (GE/Siemens/Philips), T1+T2+SWI+fMRI+dMRI, BIDS on OpenNeuro

Motion / reliability

• MR-ART — 148 adults x 3 T1 (still / low-motion / high-motion), OpenNeuro, useful for motion robustness studies

• AHEAD — 105 subjects, 7T submillimeter quantitative MRI, 18-80 yr, open on figshare
• Edlow 100-micron ex-vivo — 1 cadaver brain at 100 um isotropic resolution, 7T, 100 hours scan time

Global geographic coverage

• BrainLat — 780 participants, 5 Latin American countries, sMRI+rsfMRI+dMRI+hd-EEG, open Sci Data 2023
• Nigerian Clinical-MRI — 88 subjects HC/dementia/PD, first open labeled African brain MRI, Sci Data 2025
• IBID (Iran) — 300 healthy 20-70 yr, multimodal, balanced by decade, ENIGMA member
• Czech Brain Aging Study — longitudinal atrophy + WM study, Prague, only longitudinal of its kind in CZ

Notes

• All entries follow the existing bullet-list format of the repository
• Access information and primary citations included for each entry
• This PR is independent of PR Restructure README into sortable tables; add clinical and tumor cohorts #7 (which restructures to tables) and can be merged separately
