Relaunch

Relaunching pipelines is a great way to quickly troubleshoot or make use of Nextflow's resume functionality and relaunch the same pipeline with different parameters.

The Resume option is selected by default when relaunching a new pipeline from the Runs monitoring screen. In short, This option allows for the continuation of a workflow execution using Nextflow resume.

For a detailed explanation of how the resume option works, please visit Part 1 and Part 2 of the Demystifying Nextflow resume description in the Nextflow blog.

Change compute environment when resuming a run

Available from Tower 22.4.0

Users with appropriate permissions can change the compute environment when resuming a run. The new compute environment must have access to the original run work directory. This means that the new compute environment must have a work directory that matches the root path of the original pipeline work directory, e.g. if the original pipeline work directory is s3://foo/work/12345, the new compute environment must have access to s3://foo/work.
