To overcome this, the publishing logic we have implemented for use with DSL2 modules attempts to minimise changing the `publishDir` directive (default: `params.outdir`) in favour of constructing and appending the appropriate output directory paths via the `saveAs:` statement e.g. ```nextflow - publishDir "${params.outdir}", - mode: params.publish_dir_mode, - saveAs: { filename -> saveFiles(filename:filename, options:params.options, publish_dir:getSoftwareName(task.process), publish_id:meta.id) } +publishDir "${params.outdir}", + mode: params.publish_dir_mode, + saveAs: { filename -> saveFiles(filename:filename, options:params.options, publish_dir:getSoftwareName(task.process), publish_id:meta.id) } ``` The `saveFiles` function can be found in the [`functions.nf`](software/fastqc/functions.nf) file of utility functions that will be copied into all module directories. It uses the various publishing `options` specified as input to the module to construct and append the relevant output path to `params.outdir`.
