# BrainAge Golden Raw MRI Dataset

Curated collection of **6,152 healthy-brain T1-weighted MRI scans** spanning
ages 0–86 years, assembled from 12 public neuroimaging datasets.

## Splits

| Split | Subjects | Age range | Size |
|-------|----------|-----------|------|
| `Golden-0-to-25/` | 4,782 | 0 – 25 y | ~42 GB |
| `Golden-25plus/` | 1,370 | 25 – 86 y | ~13 GB |

## Source datasets

BCP, Calgary, ds002726, ds000248, PTBP, IXI, MPI-Leipzig,
AOMIC-ID1000, NKI-Rockland, ABIDE-I, ABIDE-II, ADHD-200.

## File format

Each scan is a `.nii.gz` NIfTI file (native space, T1w).
Manifests (`manifest.csv`) list subject IDs, dataset of origin,
chronological age, sex, split, and file paths.

## Intended use

Training and evaluating brain-age prediction models on healthy controls.
