# ReLiSS

Inference, evaluation, completed-run logs and fixed data splits:
[hekaiwang/ReLiSS](https://github.com/hekaiwang/ReLiSS).

Training code and the complete experiment pipeline are not included in this release.

| Dataset | Protocol | Checkpoints | Channel order |
|---|---|---|---|
| BraTS2021 | Five folds, 1,251 subjects | fold 0–4, best | T1, T1ce, T2, FLAIR |
| ISLES2022 | Five folds, 250 subjects | fold 0–4, final | FLAIR, ADC, DWI |
| WMH2017 | Official 60 train / 110 test | fold all, final | FLAIR, T1 |

This repository contains eleven training checkpoints, matching plans,
dataset metadata and splits. WMH uses the official train/test protocol; the
training split file does not imply five released WMH models.

`weights_manifest.json` and `SHA256SUMS` record checkpoint sizes and SHA-256.
The checkpoint tensors and training state are preserved. The trainer
folder name is `nnUNetTrainerReLiSS_300epochs`; the supplied inference
script directly constructs the matching network and loads its state dictionary.

## Download

From the installed code repository:

```bash
source scripts/env.sh
python scripts/download_weights.py --repo wanghekai/ReLiSS \
  --revision COMMIT_HASH --output "$nnUNet_results"
```

Replace `COMMIT_HASH` with the immutable model revision in the code repository's
`docs/WEIGHTS.md`. The downloader fetches exactly eleven weights and verifies
sizes and hashes. Follow the code README for held-out inference and evaluation.
For cross-validation, use each subject's held-out fold. Missing channels are
zeroed after full-input preprocessing; the released protocol uses a shared crop.

Project code and model release are MIT licensed. Dataset and dependency terms
remain separate. Obtain MRI data and reference masks from their authorized
