• This record is derived from hrf: HRF-Seg+ adds multi-structure annotations to the 45 HRF images. (evidence)

Access information and download

CLI

# Read-only preflight
eyehub download hrf_seg_plus --data-dir ./data --dry-run --json

# Download, only when preflight reports supported behavior
eyehub download hrf_seg_plus --data-dir ./data

Python

from eyedatahub.acquisition import preflight_dataset
from eyedatahub.datasets.registry import REGISTRY

ds = REGISTRY.get_dataset('hrf_seg_plus')
print(preflight_dataset(ds, './data'))  # no download
