Troubleshooting Tips

After a pipeline run is completed, Nextflow produces a set of logs and reports. They contain information about the execution of the pipeline and can serve as a helpful resource for debugging.

The files are the following:

• Dag.html - a graphic visualization of your pipeline, edges are labeled with data transfer channel names and nodes are capsule job names.

• Netflow.log - text file with detailed information about the execution of the pipeline. This is the one of the most comprehensive files and the best place to find specific technical errors that caused your pipeline to fail.

• Report.html - an HTML version of nextflow.log. This report will contain information about resource metrics and at which capsule jobs the pipeline failed.

• Trace.txt - run status of each job and information and simple metrics for each job

• Timeline.html - report for timeline of all jobs in your pipeline
