3. Loop on List of Columns

Loop on List of Columns

This workflow reads the dataset created by the the workflow named "Counting Loop 2".
1. Of all the Cluster_Membership columns only one is kept (they are all the same anyway).
2. Columns from different iterations (#iter i) are then processed differently.

To do that we loop over all columns and one by one we process them using a Column List Loop Start node.
