This command can be used to set the value of a pipeline parameter to a specified value as defined by the user. This value can be any type of signal in that given workspace. This command can be found under Pipeline Control in the pipeline workshop.
The command below is as seen on the Visual3D application.
Set_Pipeline_Parameter_To_Data_Value /SIGNAL_TYPES= ! /SIGNAL_FOLDER=ORIGINAL ! /SIGNAL_NAMES= ! /SIGNAL_COMPONENTS=ALL_COMPONENTS /PARAMETER_NAME= ;
The following table shows the command parameters and descriptions:
| SIGNAL_TYPES | The type of signal you wish to set as the parameter value, e.g. LINK_MODEL_BASED |
| SIGNAL_FOLDER | Corresponding Folder e.g. PROCESSED |
| SIGNAL_NAMES | Name of the Desired signal |
| SIGNAL_COMPONENTS | Components of the desired Signal, default is all components |
| PARAMATER_NAME | Name for new parameter |
Create a parameter called SUBJECT_ID based on subject names stored in PARAMETERS:SUBJECT:NAMES.
