## @dugla/swc
@dugla/swc is  CLI (command line tool) to support the [SpaceWalk](https://github.com/igvteam/spacewalk) project. 
Use this tool to convert a legacy ensemble or point-cloud file to the file format supported by [SpaceWalk](https://github.com/igvteam/spacewalk).

## Requirements
- Node >= v10.13.0
- NPM >= v6.9.0

### Installation
````
npm install -g @dugla/swc
````

### Usage

``cd`` to the location of the file to be converted

If a point cloud file is being converted:

``swc --pointcloud filename --output filename [--dir output-directory] --chromosome name --genome-assembly assembly``

If an ensemble file is being converted:

``swc --ensemble filename --output filename [--dir output-directory] --chromosome name --genome-assembly assembly``

Options have the following aliases. Either may be used:

```
--pointcloud, -p
--ensemble, -e
--output, -o
--dir, -d
--chromosome, -c
--genome-assembly, -g
```

The default output directory is the current directory. Include ``--dir output-directory`` to  specify a different directory.
