# PISCES-CulledPDB
Curated protein chain tables from PISCES/CullPDB: one row per chain with sequence and metadata.
**Dataset:** [PRMegathon26/PISCES-CulledPDB](https://huggingface.co/datasets/PRMegathon26/PISCES-CulledPDB)
Use the **subset dropdown** in the Hugging Face Data Viewer to switch between the main table and 242 curation subsets.
## Summary
| Item | Description |
|------|-------------|
| **Main CSV** | `curated_csv/cullpdb_combined_chains.csv` — full chain table |
| **Subsets** | `curated_csv/subsets/*.csv` — 242 files (same columns) |
| **Index** | `curated_csv/cullpdb_list_fasta_index.csv` |
Full list of subset paths: `curated_csv/dataset_metadata.json` (keys `data_paths`, `subset_paths`).
## Columns (chain CSVs)
| Column | Description |
|--------|-------------|
| **pdb_chain** | PDB chain ID (e.g. 1ABC_A) |
| **pdb** | PDB ID (first 4 chars) |
| **chain** | Chain ID |
| **sequence** | Amino acid sequence (one-letter) |
| **len** | Sequence length |
| **method** | Experimental method (e.g. XRAY, NMR) |
| **resolution** | Resolution in Å (per structure) |
| **rfac** | R-factor |
| **freerfac** | Free R-factor |
| **pc** | Sequence identity cutoff % used for this subset |
| **no_breaks** | Whether chain has no breaks (yes/no) |
| **R** | R-factor cutoff used for this subset |
| **source_list** | Subset list basename (identifies curation parameters) |
## Usage
```python
from huggingface_hub import hf_hub_download
import pandas as pd
path = hf_hub_download(repo_id="PRMegathon26/PISCES-CulledPDB", filename="curated_csv/cullpdb_combined_chains.csv", repo_type="dataset")
df = pd.read_csv(path)
```
