+## Data
+
+The `data/` directory contains 10,631 RNA sequences together with 3D structures predicted by trRosettaRNA2 and per-residue pLDDT scores.
+
+```
+data/
+├── metadata.csv                 # one row per RNA
+└── trran_data_publish.tar.gz    # trRosettaRNA2-predicted structures (539 MB)
+```
+
+### `metadata.csv`
+
+| Column | Description |
+|---|---|
+| `name` | Entry ID, also the directory name inside the archive (e.g. `000011_bpRNA_RFAM_7168_L89`) |
+| `original_task_id` | Task ID from the original prediction pipeline |
+| `source_db` | Source database: `bpRNA-1m90` (6,458) or `RNAStrAlign` (4,173) |
+| `source_id` | ID of the entry in the source database |
+| `length` | Sequence length (16–252 nt, median 77) |
+| `mean_plddt` | Mean pLDDT over all residues (0.80–0.99) |
+| `min_residue_plddt` | Minimum per-residue pLDDT |
+| `max_residue_plddt` | Maximum per-residue pLDDT |
+| `cluster_rep_id90_cov95` | Cluster representative at 90% sequence identity / 95% coverage (10,139 clusters) |
+| `sequence` | RNA sequence |
+
+### `trran_data_publish.tar.gz`
+
+Each entry in `metadata.csv` has one directory in the archive:
+
+```
+trran_data_publish/
+└── <name>/
+    ├── model_1_relaxed200.pdb   # 3D structure predicted by trRosettaRNA2
+    └── plddt.csv                # per-residue pLDDT (columns: Residue_Index, pLDDT)
+```
+
+### Download

+hf download GENTEL-Lab/La-Ribo --include "data/*" --local-dir La-Ribo
