CWL User Guide 3: Essential Input Parameters をやってみた

Last updated at Posted at 2017-12-02

CWL User Guide 3: Essential Input Parameters

Common Workflow Language User Guide: Essential Input Parameters

今回は、入力パラメータの取扱について書いてあります

以下のようなことが解説されています。

  • inputs
  • id
  • type
  • class
  • File
  • path
  • inputBinding
  • prefix
  • separate
  • prefixと値を結びつけるときに、空白をいれるかどうかのフラグ
  • baseCommand
  • /tmp ディレクトリはどうしてできるのか?

用語の数は結構ありますが、1つ1つ短い解説なのとサンプルがあるのでよいとおもいます

CWLファイル、inp.cwl

#!/usr/bin/env cwl-runner

cwlVersion: v1.0
class: CommandLineTool
baseCommand: echo
inputs:
  example_flag:
    type: boolean
    inputBinding:
      position: 1
      prefix: -f
  example_string:
    type: string
    inputBinding:
      position: 3
      prefix: --example-string
  example_int:
    type: int
    inputBinding:
      position: 2
      prefix: -i
      separate: false
  example_file:
    type: File?
    inputBinding:
      prefix: --file=
      separate: false
      position: 4

outputs: []

パラメータファイル、inp-job.yml

inp-job.yml
example_flag: true
example_string: hello
example_int: 42
example_file:
  class: File
  path: whale.txt

実行に必要なファイル whale.txt

空のファイルを

touch whale.txt

で、作ると買いてありました

実行

実行方法

cwltool inp.cwl inp-job.yml

出力

$ cwltool inp.cwl inp-job.yml
