Last updated at Posted at 2017-12-05

CWL User Guide 6: Parameter References

Common Workflow Language User Guide: Parameter References

今回は、パラメータを別の場所からもってくる方法について書かれています
またさらっとですがJavascript 文法のサブセットを使うことが示されています

第4回で作った hello.tar を一回消してあらたにつくるという流れで紹介されています。

この回にでてくる主なキーワード

  • $(...) Javascript

CWLファイル、tar-param.cwl

tar-param.cwl
#!/usr/bin/env cwl-runner

cwlVersion: v1.0

  tarfile:
    type: File
    inputBinding:
      position: 1
  extractfile:

    inputBinding:
      position: 2
outputs:
  example_out:
    type: File
    outputBinding:
      glob: $(inputs.extractfile)

パラメータファイル tar-param-job.yml
