# MotionMamba2.0 G1 Mixed Motion CSV
Accepted G1 motion exports from BONES Seed, HiPHI and HumanML3D. BONES uses
official G1 CSV input; HiPHI and HumanML3D are retargeted to G1. All packaged
motions are sampled at **25 FPS**. The package contains **179,648 motions**,
**660.98 hours**, and their available text descriptions.
| Split | Motions | Hours | Uncompressed CSV bytes |
|---|---:|---:|---:|
| Train | 156,819 | 588.922356 | 24,775,677,931 |

## Files
Files are stored directly in the repository root:
- `data/{train,val,test}/{source}-NNNN.tar.gz`: sharded CSVs and original motion
JSON sidecars. Shards contain only one source and one split. Approximately
512 MiB of uncompressed CSV data is assigned to each full shard.
- `metadata/{train,val,test}.jsonl`: portable sample metadata, captions, splits,
archive locations, extracted file locations, and original file SHA-256s.
- `dataset_info.json`: measured counts, sizes, source-manifest hashes and shard
checksums.
Archive members retain readable source sample names, for example
`motions/train/bones/Idle_Left_001__A017.csv`. Characters that cannot be used
safely in file paths are percent-encoded. Each metadata row gives the corresponding `sample_id`,
`archive_path`, `csv_path` and `sidecar_path`. Paths are relative to the release
directory; metadata does not depend on the original server's directory layout.
The original sidecars retain their historical provenance fields.
The package does not include intermediate solver caches, videos, original
BVH/SMPL inputs, `qpos.npy`, or the precomputed 414-dimensional `features.npy`.
## Download and extract
This repository is public; no login is required for downloading.
```python
from huggingface_hub import snapshot_download
snapshot_download(
repo_id="AIGeeksGroup/MotionMamba2.0",
repo_type="dataset",
local_dir="MotionMamba2.0",
)
```
To download through HF-Mirror, set `HF_ENDPOINT=https://hf-mirror.com` before
running the downloader. Uploads are made to the official Hugging Face endpoint.
Extract shards inside the release directory so that their paths agree with the
metadata:
```bash
cd MotionMamba2.0
for shard in data/*/*.tar.gz; do tar -xzf "$shard"; done
```
## CSV representation
Each CSV has **36 columns**: frame index, three root translations, three root
Euler angles, and 29 joint angles. Each CSV contains its ordered column names
in the header row; units and rotation conventions are described below.
- Frame indices start at zero; time is `Frame / 25` seconds.
- Root translation is in **centimetres**; multiply by `0.01` for metres.
- Root Euler angles and articulated joint angles are in **degrees**; convert
with `numpy.deg2rad` when a consumer expects radians.
- Root Euler convention: SciPy lowercase extrinsic active `xyz`.
- CSV root Euler coordinates are distinct from quaternion-based MuJoCo qpos.
```python
import json
from pathlib import Path
import numpy as np
release = Path("MotionMamba2.0")
with (release / "metadata/train.jsonl").open() as f:
sample = json.loads(next(f))
motion = np.loadtxt(release / sample["csv_path"], delimiter=",", skiprows=1,
ndmin=2)
root_translation_m = motion[:, 1:4] * 0.01
root_euler_xyz_rad = np.deg2rad(motion[:, 4:7])
joint_angles_rad = np.deg2rad(motion[:, 7:])
captions = sample["captions"]
```
