Collapsing Tasks

Addition of  task and respective resulting data nodes to project may lead to creation of long pipelines, extending well beyond the border of the canvas (Figure 18). 

...

In that case, the pipeline can be collapsed, to hide the steps that are (no longer) relevant. For example, once the single-cell RNA-seq data has been quantified, Single cell counts data node will be a new analysis start point, as the subsequent analyses will not focus on alignment, UMI deduplication etc. To start, right-click on the task node which should become a boundary (=end) of the collapsed portion of your pipeline and select Collapse tasks (Figure 19).

...

All the tasks on that layer will turn purple. Then left-click the task which should be the other boundary of the collapsed portion. The All the tasks that will be collapsed will turn green and a dialog will appear (Figure 19). In the example shown in Figure 19, the tasks between Trim tags and Quantify barcodes will be collapsed. Give the collapsed section a name (up to 30 characters) and select Save (Figure 20).

...

The collapsed portion of the pipeline is replaced by single task node, with a custom label ("Single cell preprocessing"; Figure 21). To re-expand the pipeline double click on the task node representing the collapsed portion of the pipeline.
