Sometimes it is useful to form ‘groups’ or ‘categories’ of nodes. With Netica, you can create groups of nodes, and to assign a name and color to each. Note: A related concept is to group states of a single node.
For instance, to clearly show the divisions between various parts of your Bayes net, you can make each subsection a different color.

Or, if there is a set of nodes that you repeatedly use for some operation (for example, a subset of nodes that you often want to remove the findings from), you can set those nodes as a node-set. Whenever you want to do the operation, you have Netica select the nodes in that node-set, and then you choose the operation from the menu.
A node may belong to several different node-sets at once, so in that case Netica needs a way to choose which node-set color to use when coloring it. Node-sets have a priority ordering, so you can choose the most important criteria to use in coloring them, which you may want to change from time to time to view the net in different ways.
The node-set options are:
• Adding and Removing Nodes from Node-Sets
• Using Node-Sets to Select Nodes
