| # 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 |
|
|

| 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) |
