This is a local derivative of medarc/adni-mini-v1-3.

It preserves the v1.3-r2 row order, metadata columns, labels, image geometry, and float32 values inside the brain. The only image change is:

image[synthseg_dseg == 0] = 0.0

The brain mask is therefore defined strictly as nonzero labels in the matching SynthSeg discrete segmentation.

See comparison.json and per_scan_stats.csv for measured storage and mask statistics. This derivative is not the official MedARC artifact.
