and then select the property from the submenu:
Arcs
Specifies the addition or removal of arcs for the currently active Bayesian network. If an arc removal is specified, it will precede any addition of an arc.
Before adding arcs, any constraints applicable to the active Bayesian network and the Temporal Indices will be checked. If a specified arc addition is inconsistent with the existing constraint, the arc won't be added.
Syntax Examples:
N1->N2=
true
adds an arc from N1 to N2N1->N2=
false
removes the arc from N1 to N2N1<-N2=
true
adds an arc from N2 to N1 (note the reversal of the arrow symbol<-
produces an arc in the opposite direction).Note that you need to add an escape character
\
before any spaces in node names. Otherwise, a space will be interpreted as a delimiter:N\ 1->Node\ 2=
true
adds an arc from N 1 to N 2Instead of the
->
characters, you can also use space=
, and--
as a delimiter between the start node and end node. With these alternative delimiters, the order of the nodes determines the arc direction.N1 N2=
true
adds an arc from N1 to N1N1=N2=
true
adds an arc from N1 to N2N1--N2=
true
adds an arc from N1 to N2N1 N2=
true
adds an arc from N1 to N2
Forbidden Arcs
Specifies the addition or removal of Forbidden Arcs between nodes and classes
Syntax Examples:
N1->N2
adds a Forbidden Arc from N1 to N2N1--N2
adds a Forbidden Arc between N1 and N2ClassA->ClassB
applies Forbidden Arcs from any nodes in ClassA to any nodes in ClassBN1
N2
removes any existing Forbidden Arc between N1 and N2. Note the space in the syntax, which triggers the removal of the Forbidden Arc.
Arc Comments
Adds, updates, or removes Arc Comments to arcs in the active network. Arc Comments are stored in HTML format.
Syntax Examples:
N1->N2=<p>This is a sample <b>Arc Comment</b>.</p>
adds an Arc Comment to the arc between N1 and N2.N1->N2=
removes an existing Arc Comment from the arc between N1 and N2.The added Arc Comment can be edited in the Arc Editor:
Arc Contextual Menu > Edit
Arc Colors
Defines colors for arcs in the active network. You can specify the color for each arc individually by providing the hex code of the color
Syntax Examples:
N1->N2=000000
changes the color of the arc between N1 and N2 to black.N1->N2=FF0000
changes the color of the arc between N1 and N2 to bright red.Note that there is no option to revert an arc color to the default color. When changing Arc Colors via a Dictionary, the colors must always be specified explicitly.
Structural Priors
Assigns Structural Priors to arcs in the active network.
Fixed Arcs
Applies Fixed Arcs to the active network or removes them.
Syntax Example:
N1->N2=true
changes the arc between N1 and N2 to a Fixed Arc.N1->N2=false
changes the arc between N1 and N2 to a normal, non-fixed arc.
