Results folder

}
Nextflow log, metrics and reports
By default, Nextflow will create a log file in the working directory called .nextflow.log. This file is hidden but you can see it using the command:
ls -a
If you rerun the pipeline in the same folder, the previous .nextflow.log will be renamed .nextflow.log.1 and a new .nextflow.log will be generated.
You can change the default location by specifying a different location
nextflow -log ~/code/nextflow.log run
You can list the execution logs of previous invocations of all pipelines in a directory by running the command:
nextflow log

If we want to get more information about an individual run we can add the run name or session ID to the log command.
For example:
nextflow log agitated_bose
