Tools Organization

Each tool is self-contained in its own directory with:

• CWL tool definition
• Dockerfile for reproducible environment
• Documentation including Docker image information

Available Pipelines

Pipelines are organized by analysis type. Each pipeline includes its own documentation and testing protocols.

Requirements

• CWL runner (e.g., cwltool, toil, cromwell)
• Docker support
• Python 3.8+

Quick Start

1. Clone the repository:

git clone [repository-url]
cd cwl-pipelines

2. Choose a pipeline and run with your preferred CWL runner:

cwl-runner pipelines/<category>/<pipeline>/<pipeline>.cwl inputs.yml

Docker Configuration

Each tool includes its own Dockerfile and documents:

• Registry location
• Image tag
• Build instructions
• Version information

Contributing

1. Fork the repository
2. Create a feature branch
3. Commit your changes
4. Submit a pull request

When adding new tools:

1. Create a new directory under appropriate category
2. Include CWL definition, Dockerfile, and README
3. Document Docker image information
4. Add tests if applicable

Testing

Each pipeline includes:

• Pipeline-specific testing documentation
• Test datasets references
• Validation criteria
• Platform-specific testing notes

Platform Support

These pipelines are tested and supported on:

• Seven Bridges Platform
• Local execution with cwltool
• [Other supported platforms]

See docs/platforms/ for implementation guides.
