* *Module*: A `process`that can be used within different pipelines and is as atomic as possible i.e. cannot be split into another module. An example of this would be a module file containing the process definition for a single tool such as `FastQC`. This repository has been created to only host atomic module files that should be added to the `tools` sub-directory along with the required documentation, software and tests.

* *Sub-workflow*: A chain of multiple modules that offer a higher-level of functionality within the context of a pipeline. For example, a sub-workflow to run multiple QC tools with FastQ files as input. Sub-workflows should be shipped with the pipeline implementation and if required they should be shared amongst different pipelines directly from there. As it stands, this repository will not host sub-workflows.

|
**The definition and standards for module files are still under discussion
|
||||||
|
amongst the community. Currently the following points have been agreed on:**
|
||||||
|
|
||||||
|
The key words "MUST", "MUST NOT", "SHOULD", etc. are to be interpreted as described in [RFC 2119](https://tools.ietf.org/html/rfc2119).
|
||||||
|
|
||||||
|
### Defining inputs, outputs and parameters
|
||||||
|
- A module file SHOULD only define inputs and outputs as parameters. Additionally,
|
||||||
|
- it MUST define threads or resources where required for a particular process using `task.cpus`
|
||||||
|
- it MUST be possible to pass additional parameters to the tool as a command line string via the `params.<MODULE>_args` parameter.
|
||||||
|
- All NGS modules MUST accept a triplet [name, single_end, reads] as input. The single-end boolean values MUST be specified through the input channel and not inferred from the data e.g. [here](https://github.com/nf-core/tools/blob/028a9b3f9d1ad044e879a1de13d3c3a25a06b9a7/nf_core/pipeline-template/%7B%7Bcookiecutter.name_noslash%7D%7D/modules/nf-core/fastqc.nf#L13).
|
||||||
|
- Process names MUST be all uppercase.
|
||||||
|
- Each process MUST emit a file `<TOOL>.version.txt` containing a single line with the software's version in the format `v<VERSION_NUMBER>`.
|
||||||
|
- All outputs MUST be named using `emit`.
|
||||||
|
|
||||||
|
### Atomicity
|
||||||
|
- Software that can be piped together SHOULD be added to separate module files unless there is an run-time, storage advantage in implementing in this way e.g. `bwa mem | samtools view -C -T ref.fasta` to output CRAM instead of SAM.
|
||||||
|
|
||||||
|
### Publishing results
|
||||||
|
- The module MUST accept the parameters `params.out_dir` and `params.publish_dir` and MUST publish results into `${params.out_dir}/${params.publish_dir}`.
|
||||||
|
- The `publishDirMode` MUST be configurable via `params.publish_dir_mode`
|
||||||
|
- The module MUST accept a parameter `params.publish_results` accepting at least
|
||||||
|
- `"none"`, to publish no files at all, and
|
||||||
|
- `"default"`, to publish a sensible selection of files.
|
||||||
|
|
||||||
|
It MAY accept further options.
|
||||||
|
- To ensure consistent naming, files SHOULD be renamed according to the `$name` variable before returning them.
|
||||||
|
|
||||||
### Testing
|
### Testing
|
||||||
|
- Every module MUST be tested by adding a test workflow with a toy dataset.
|
||||||
|
- Test data MUST be stored within this repo. It is RECOMMENDED to re-use generic files from `tests/data` by symlinking them into the test directory of the module. Specific files MUST be added to the test-directory directly. Test files MUST be kept as tiny as possible.
|
||||||
|
|
||||||
If you want to add a new module config file to `nf-core/modules` please test that your pipeline of choice runs as expected by using the [`-include`](https://www.nextflow.io/docs/edge/dsl2.html#modules-include) statement with a local version of the module file.
|
### Software requirements
|
||||||
|
- Software requirements SHOULD be declared in a conda `environment.yml` file, including exact version numbers. Additionally, there MUST be a `Dockerfile` that containerizes the environment, or packages the software if conda is not available.
|
||||||
|
|
||||||
|
### File formats
|
||||||
|
- Wherever possible, [CRAM](https://en.wikipedia.org/wiki/CRAM_(file_format)) files SHOULD be used over BAM files.
|
||||||
|
- Wherever possible, FASTQ files SHOULD be compressed using gzip.

||||||
