The clustering modules functionality allows for a researcher to select a group of connected modules, and abstract them as a single node. This action clusters them together, and nests the resulting pipeline as a sub-pipeline in the current pipeline.

To cluster a group of modules

• select the modules
• right-click to bring up the context menu
• click "Group modules"
  

• This will generate a grouped pipeline with all of the modules selected inside
  

• If the group of modules selected by the researcher rely on a module not currently selected, the grouping option will be disabled.
  

To ungroup a pipeline.

• right-click the pipeline you want to ungroup to bring up the context menu
• click "Ungroup"
  
• All of the modules inside the grouped pipeline will now be placed in the current pipeline.
