Exclude

Context

The Exclusion function allows you to temporarily exempt the selected nodes from actions that would otherwise apply to all nodes in the network graph. For instance, you can temporarily prevent nodes from being included in network learning.

During structural learning, the learning algorithm will not add any arc having an excluded node as an extremity. This is particularly useful when you wish to learn the structure of a network on a subset of nodes.

Usage

Exclusion

Select one or more nodes, then access the Exclude function using any of the following methods:

Node Contextual Menu > Exclude.
Menus > Edit > Exclude.
Hold X and double-click on any of the selected nodes to be excluded.

As a result, the excluded nodes appear in a distinct excluded style, showing the “wrong way” sign at the center of the node.

Reversal of Exclusion

To reverse an existing exclusion, select the nodes to re-include, then access the Exclude function again using any of the following methods:

Node Contextual Menu > Exclude.
Menus > Edit > Exclude.
Hold X and double-click on any of the selected nodes.

The re-included nodes will revert to the default appearance.

Propagation

The Propagate Exclusion button opens a dialog for selecting the classes associated with the node. All nodes belonging to the selected classes are then excluded or re-included accordingly.

Workflow Animation

Note that the Exclude function removes the selected nodes’ inbound and outbound arcs. While a node’s exclusion can be reverted, any arcs deleted as a result of the exclusion will not be restored.
