# US Segmentation Dataset

The dataset is a collection of openly available ultrasound datasets.

The individual datasets are stored as zip files in the `zip` directory. The utility for extraction all of them will be provided later.

## Instructions for uploading new datasets

1. Download the dataset from the source
2. Convert the dataset into a zip format if required
3. Upload the zip file corresponding anatomy folder in the `zip` directory using the command: `hf upload [repo_id] [local_path] [path_in_repo] --repo-type dataset --commit-message "add-dataset: <dataset_name>"`
    
eg: `hf upload us-segmentator/us-segmentation-dataset local_path_to_zip_file.zip zips/<anatomy_name>/<zip_file_name>.zip --repo-type dataset --commit-message "add-dataset: <dataset_name>"`

## Instructions for downloading the dataset

### CLI
1. Make sure you have git lfs installed
2. Run the following command:
```bash
git lfs install
```
3. Run the following command:
```bash
hf download us-segmentator/us-segmentation-dataset --repo-type dataset --local-dir local_path_to_download_directory
```
4. The dataset will be downloaded to the local directory.

> Note: The dataset can be downloaded without the --local-dir argument, but it will be downloaded the huggingface cache directory.

### Python

Use the `huggingface_hub` library to download specific files programmatically:

```python
from huggingface_hub import hf_hub_download

file_path = hf_hub_download(
    repo_id="us-segmentator/us-segmentation-dataset",
    filename="zips/<anatomy_name>/<zip_file_name>.zip",
    repo_type="dataset",
    local_dir="local_path_to_download_directory"
)

print(f"File downloaded to: {file_path}")
```

## Pulling non-LFS changes only

If you are only pulling repository updates like `README.md`, scripts, or other small files (and want to skip downloading large LFS zip datasets during pull), use:
Use case: This is useful when you are contributing documentation/code changes and do not need the dataset zip files on your machine.

### Linux/macOS

```bash
GIT_LFS_SKIP_SMUDGE=1 git pull
```

### Windows (PowerShell)

```powershell
$env:GIT_LFS_SKIP_SMUDGE=1
git pull
```
