This course will take place over two half-day sessions, held exclusively in the afternoons.

Overview

The rapid evolution of computational infrastructure to perform bioinformatics analysis and the claim for more efficient and reproducible workflows have opened a door to include new tools that optimize pipeline execution. The workflow orchestrator Nextflow has arisen as a great alternative to meet these needs given its native capabilities such as the possibility to run the software independently and in parallel, the chance to couple it to many other modules or pipelines and its scalability.

This course empowers the participants with hands-on strategies to wrap their pipelines with Nextflow, streamlining the analysis and allowing a plug-and-play modular design. In addition, the participants will learn to take advantage from other Nextflow features such as the possibility of choosing the software management technology or using different executors from local environments until High Performance Clusters.

Audience

This course is designed for PhD students, postdoctoral and other researchers in the life sciences from both academia and industry who aim at automatizing their analyses and/or in the quest to guarantee scalability and reproducibility of their pipelines through a workflow manager.

Learning outcomes

At the end of the course, the participants are expected to:

• Explain the benefits of wrapping routine analyses in a workflow orchestrator such as Nextflow.
• Construct Nextflow pipelines incrementally, adding new features at each stage.
• Apply modularization to design components that can be reused across pipelines.
• Implement operators and control-flow statements to define pipeline behaviour under different conditions.
• Integrate custom scripts and external tools into a pipeline to take advantage of advanced Nextflow features.
• Develop Nextflow pipelines for their own analyses that follow current community standards, such as the FAIR principles.
