Associate Dictionary — Node

**Node Renaming allows renaming each node with a new name.
Comments allows associating a Comment with each node that is in the file.
Classes allows organizing nodes in subsets called Classes . A node can belong to several Classes at the same time. These classes allow generalizing some node's properties to the nodes belonging to the same classes. They allow also creating constraints over the arc creation during learning.
Colors allows associating colors with the nodes or Classes that are in the file. The colors are specified as 9-bit RGB with 8 bits by channel in hexadecimal format (web format). For example, the color red corresponds to an RGB value of 255, 0, 0 or Hex #FF0000.
Images allows associating colors with the nodes or Classes that are in the file. The images are represented by their path relatively to the directory where the dictionary is.
Costs allows associating with each node a Cost. A node without a Cost value is also considered Not Observable.
Temporal Indices allows associating Temporal Indices with the nodes that are in the file. The Temporal Indices are used by BayesiaLab's learning algorithms to take into account any constraints regarding possible probabilistic relationsships, such as not to add any arcs arcs between future nodes and past nodes. The rule that is used to add an arc from node N1 to node N2 is:
- If the temporal index of N1 is positive or null, then the arc from N1 to N2 is only possible if the temporal index of N2 is greater of equal to the index of N1.
Local Structural Coefficients allows setting the Local Structural Coefficient of each specified node or each node of each specified Class.
State Virtual Numbers allows setting State Virtual Numbers for each specified node or all nodes in a specified Class.
Locations allows setting the position of node on the Graph Panel.
