Summary log
paramsSummaryLog()
This function returns a string that can be logged to the terminal, summarizing the parameters provided to the pipeline.
Note
The summary prioritizes displaying only the parameters that are different the default schema values.
Parameters which don't have a default in the JSON Schema and which have a value of null, "", false or 'false' won't be returned in the map.
This is to streamline the extensive parameter lists often associated with pipelines, and highlight the customized elements.
This feature is essential for users to verify their configurations, like checking for typos or confirming proper resolution,
without wading through an array of default settings.
The function takes two arguments:
- The
WorkflowMetadataobject,workflow(required) - File name of a schema file (optional, default:
nextflow_schema.json).
Typical usage:

Coloured logs
By default, the summary output is coloured using ANSI escape codes.
If you prefer, you can disable these by using the argument monochrome_logs, e.g. paramsHelp(monochrome_logs: true). Alternatively this can be set at a global level via parameter --monochrome_logs or adding params.monochrome_logs = true to a configuration file. Not --monochromeLogs or params.monochromeLogs is also supported.
paramsSummaryMap()
This function returns a Groovy Map summarizing parameters/workflow options used by the pipeline. As above, it only returns the provided parameters that are different to the default values.
This function takes the same arguments as paramsSummaryLog(): the workflow object and an optional schema file path.
Note
Parameters which don't have a default in the JSON Schema and which have a value of null, "", false or 'false' won't be returned in the map.
