# ​​Standalone Mode​

## Introduction

SDAS\_pipeline\_subprocess.py provides a simple way to run most SDAS modules on a single server with a single click.

## System Requirements

* Python 3.6+
* SDAS software properly configured
* Server configuration must meet [SDAS system configuration requirements](https://mysite.gitbook.io/sdas_manual_eng/02_install#id-1.-system-configuration-requirements).

## Usage Steps

### 1. Configure pipeline\_input.conf File

See [Cluster Submission Mode​ Configuration](https://mysite.gitbook.io/sdas_manual_eng/readme/02_qsub#id-1.-configure-pipeline_input.conf-file)

### 2. Run with a single click

-c specifies the configuration file, -o specifies the output folder:

```bash
python SDAS_pipeline_subprocess.py -c pipeline_input.conf -o ./output
```

#### Single-Slice Data Testing:

```bash
python SDAS_pipeline_subprocess.py -c pipeline_input.single_slice.conf -o ./output_single
```

#### Multiple-Slice Data Testing: 

```
python SDAS_pipeline_subprocess.py -c pipeline_input.multiple_slice.conf -o ./output_multi
```
