Execute a workflow
$ nextflow run main.nf
Re-run using cached results
$ nextflow run main.nf -resume
Execute with a specific configuration file
$ nextflow run main.nf -c nextflow.config
Supply a custom parameter
$ nextflow run main.nf --param "value"
Use a pre-defined configuration profile
$ nextflow run main.nf -profile uppmax
Use Docker or Apptainer
$ nextflow run main.nf -with-docker $ nextflow run main.nf -with-apptainer
