Reproducibility and package management : workflow languages (CWL, Snakemake, Conda).

Workflows and Package Management

Reproducibility and package management techniques: workflow languages (CWL, Snakemake, and Conda). This course introduces some of the approaches for package management and how to create reproducible workflows or pipelines.

Competencies

This session seeks to impart the following competencies:

1. Knowledge and skills: Bioinformatics tools and their usage.
2. Knowledge and Skills: Command line and scripting based computing skills appropriate to the discipline.

Learning Outcomes

By the end of this session, and the projects that follow, the learner should be able to:

1. Select the best workflow and package managers based on the task at hand
2. Implement a genomic pipeline in at least one workflow manager
3. Set up a reproducible analysis environment

Outline

• Introduce the high-level concept of workflows and high throughput data analysis
• Hands-on activities for setting up the packages
• Introduce package management and how we can use conda to increase reproducibility with workflows
• Introduce the theory of workflows: with emphasis on one language (say, snakemake)
• Hands-on activities of developing workflows

Slides

1. Using Bioconda to streamline software installation for bioinformatics
