+# Cystoscopy Tumor Detection
+Cystoscopic video dataset with per-frame `tumor` bounding-box annotations, paired with patient-level clinical metadata.
+## Contents
+| Path | Description |
+|---|---|
+| `data/videos/` | 173 raw cystoscopy `.mp4` tracks (~4 GB). Filename pattern `P{NN}_cystoscopy_track_{NNN}.mp4`. |
+| `data/annotations.parquet` | Long-format bounding boxes: one row per box (69 108 rows, 444 tracks). Columns: `video_id, patient_id, track_id, frame, label, xtl, ytl, xbr, ybr, occluded, outside, keyframe, z_order`. |
+| `data/clinical_info.parquet` | One row per patient (n=30). Columns: `patient_id, histological_type, num_frames, light_mode`. |
+| `splits/{train,val,test}.txt` | Patient-grouped video-id lists (seeded shuffle, seed=42). 24 / 3 / 3 patients → 132 / 18 / 23 videos. No patient appears in more than one split. |
+## Notes
+- Box coordinates are absolute pixel coordinates in the source video frames (CVAT format).
+- `annotated_videos/` (boxes burned into the pixels) is **not** shipped — it is fully reproducible from `annotations.parquet` + `data/videos/` via the included `overlay_boxes.ipynb`.
+- Splits are by **patient** to prevent leakage; adjust by editing `splits/*.txt`.
+## Loading
+```python
+import pandas as pd, pathlib
+ann = pd.read_parquet("hf://datasets/milkyroad/B/data/annotations.parquet")
+cli = pd.read_parquet("hf://datasets/milkyroad/B/data/clinical_info.parquet")
+train_ids = pathlib.Path("hf://datasets/milkyroad/B/splits/train.txt").read_text().split()
+```
+## Reproducibility
+Splits generated with `random.Random(42)` over the sorted patient-id list (0–29).
