## Changes made to the original files

These files are modified versions of the originals, as CC BY 4.0 requires us to state.

- Intensities were rescaled to 8-bit (0–255) using the 0.5th to 99.5th percentile of non-zero
  voxels inside each template's brain mask (97th percentile ceiling for the neonatal T2).
  Geometry (affine, qform, sform) is unchanged.
- `*_preview` files are 2×2×2 block averages (labels: majority vote), with the affine shifted
  so voxel centres stay aligned with the full-resolution volume.
- dHCP structure labels: the two background labels (84, 85) were set to 0.
- dHCP structure colours were reassigned for 85 of 85 structures so that
  neighbouring structures are distinguishable. Label numbers and names are unchanged.
- UNC AAL labels: the source has no colour table or names file, so colours were assigned
  and the standard AAL region names were attached (abbreviations expanded, e.g.
  `Frontal_Inf_Tri_L` → "Inferior frontal gyrus, triangular part left").
- UNC templates are T1-weighted only.
