This directory contains the public reviewer sample for OpenBrain v1.0.
It is intended for quick inspection without downloading the full release.
## Contents
- `sample_manifest.csv`: metadata and QC-7 values for the sample.
- `cases/<case_id>/image.nii.gz`: preprocessed T1-weighted image.
- `cases/<case_id>/brain_mask.nii.gz`: SynthStrip-derived brain mask.
- `cases/<case_id>/whole_brain_segmentation.nii.gz`: released automated
whole-brain segmentation.
The sample contains 64 source-diverse cases. All sample cases are drawn
from the HighConf tier and were selected by low combined risk `R`, with
Q1/Q3/Q4 visual-cleanliness tie-breaks. The sample is therefore designed
to show high-confidence examples for reviewer preview and smoke testing.
These labels are algorithmic pseudo-labels, not manual ground truth, and
should not be used for clinical decision-making.
## Download
```bash
hf download openbrain-anon/openbrain_v1_0 \

```bash
pip install nibabel matplotlib numpy
python openbrain_v1_0_sample/sample/preview_sample_case.py \
--case-dir openbrain_v1_0_sample/sample/cases/<case_id> \
--output preview.png
