Creating Pipeline Lists

Pipeline lists allow you to specify values for multiple iterations of a module. A Pipeline list can either be specified from a file (referred to as Pipeline list file), or it can be stored as a variable within a module file.

Creating a Pipeline List File

Pipeline list files are basic text files. Each line in the file represents a unique iteration value. A pipeline list file can be viewed, edited, and created using your favorite text editor. To reference a Pipeline list file within a variable, use the "Add List URL" button when editing a variable/argument.

You can also create a variable that represents a Pipeline list file. Follow the procedure to create a new data variable and simply set the class to "Pipeline list file". From here, select the list file as you normally would when creating a file variable.

Creating a Pipeline List

A Pipeline list is a special variable that acts like an external list file, but is stored as a variable within a module file. To reference a Pipeline list variable (including Pipeline list file variables), click the "Add List Reference" button when editing a variable/argument.

To create a Pipeline list, follow the procedure to create a new data variable and set the class to "Pipeline list". A Pipeline list variable can only contain a single value tab. Each "String" in the Pipeline list variable represents a unique iteration value.

Pipeline also provides a mechanism for creating a Pipeline list variable for a "File" or "File"-derivative class variable. When selecting the file path using the file chooser, it is possible to select multiple files. If multiple files are selected, a Pipeline list variable is automatically created with unique iteration values generated for each selected file. The file variable will also contain a list reference to the generated Pipeline list file. This new variable is initially labelled "List file for: {LABEL OF ORIGINAL FILE VARIABLE}".
