# SKEMPI v2
SKEMPI v2 protein-protein binding affinity mutation dataset, normalized to newline-delimited JSON with row-level provenance.
Processed and uploaded by the [MegaData](https://github.com/) post-download pipeline
(internal repo). Original source: <https://life.bsc.es/pid/skempi2>.

## Layout
```
.
├── _MANIFEST.json # aggregate manifest (per-table counts)
└── tables/<source_slug>.jsonl # normalized rows (one JSON object per line)
```
Each line in a `tables/*.jsonl` file is a JSON object with at least
`dataset_id`, `row` (the raw upstream row), `row_index`, and `source_file`
fields, so every row carries its upstream provenance.
## Loading
```bash
hf download LiteFold/SKEMPI2 --repo-type dataset --local-dir ./skempi2
```
Programmatic streaming:
```python
import json
from pathlib import Path
from huggingface_hub import snapshot_download
local = snapshot_download(repo_id="LiteFold/SKEMPI2", repo_type="dataset")
for jsonl in sorted(Path(local, "tables").glob("*.jsonl")):
with jsonl.open() as f:
for line in f:
row = json.loads(line)
... # row["row"] is the upstream record
```
