## Raw data

| File | Unit | Description |
| --- | --- | --- |
| `data/raw/phase_diagram_original_scale.csv` | peptide | Earliest verified PhaseFlow input table with one amino-acid sequence and up to 16 PSSI measurements per row. |

The source table's required fields are `AminoAcidSequence` and `group_11` to
`group_44`, ordered row-major over a 4×4 PSSI grid. NaN represents a missing
measurement and is not a zero-valued PSSI observation.

## Scripts and configuration

`scripts/prepare_missing_splits.py` constructs the local PhaseFlow
missing-count views. `configs/training.yaml` records the best source phase-prediction
configuration; it is not a claim that the release contains model weights.
