Tool Repository

A Tool is the definition of a containerized application with defined inputs, outputs, and execution environment details including compute resources required, environment variables, command line arguments, and more.
Create a Tool
Tools define the inputs, parameters, and outputs for the analysis. Tools are available for use by any project in the account.
1.From the Tool Repository page, select New Tool.
2.Configure tool settings in the tool properties tabs. See Tool Properties.
3.Select Save.

The tool is released. Tools in this state cannot be edited. Editing is locked but the tool can be cloned to create a new version.
Deprecated
The tool is no longer intended for use in pipelines. but there are no restrictions placed on the tool. That is, it can still be added to new pipelines and will continue to work in existing pipelines. It is merely an indication to the user that the tool should no longer be used.
Documentation Tab
The Documentation tab provides options for configuring the HTML description for the tool. The description appears in the Tool Repository but is excluded from exported CWL definitions.
General Tool Tab
The General Tool tab provides options to configure the basic command line.

2.Select Edit.

Import Tool
In addition to the interactive Tool builder, the platform GUI also supports working directly with the raw definition when developing a new Tool. This provides the ability to write the Tool definition manually or bring an existing Tool's definition to the platform.
A simple example CWL Tool definition is provided below.
#!/usr/bin/env cwl-runner
​
cwlVersion: v1.0
class: CommandLineTool
label: echo
inputs:
  message:
    type: string
    default: testMessage
    inputBinding:
      position: 1
outputs:
  echoout:
    type: stdout
baseCommand:
- echo
When creating a new Tool, navigate to the Tool CWL tab to show the raw CWL definition. Here a CWL CommandLineTool definition may be pasted into the editor. After pasting into the editor, the definition is parsed and the other tabs for visually editing the Tool will populate according to the definition contents.

Creating Your First Tool - Tips and Tricks
General Tool - includes your base command and various optional configurations.
The base command is required for your tool to run, e.g. python /path/to/script.py such that python and /path/to/script.py are added in separate lines.
Inline Javascript requirement - must be enabled if you are using Javascript anywhere in your tool definition.
Initial workdir requirement - Dirent Type
Your tool must point to a script that executes your analysis. That script can either be provided in your Docker image or using a Dirent. Defining a script via Dirent allows you to dynamically modify your script without updating your Docker image. In order to define your Dirent script define your script name under Entry name (e.g. runner.sh) and the script content under Entry. Then, point your base command to that custom script, e.g. bash runner.sh.
❗️ What's the difference between Settings and Arguments?
Settings are exposed at the pipeline level with the ability to get modified at launch, while Arguments are intended to be immutable and hidden from users launching the pipeline.
How to reference your tool inputs and settings throughout the tool definition?
You can either reference your inputs using their position or ID.
Settings can be referenced using their defined IDs, e.g. $(inputs.InputSetting)
File/Directory inputs can be referenced using their defined IDs, followed by the desired field, e.g. $(inputs.InputFile.path). For additional information please refer to the File CWL documentation.
All inputs can also be referenced using their position, e.g. bash script.sh $1 $2
