*Function: Create and modify Bayesian networks.

*Command line activation
	Make "\exe" the current directory and start
 the tool by "java BNetEdit.BNetEdit".

*Use of buttons
-Draw: 
 	Draw DAG dependency structure.
       	Each drawing action defines a parent, a child
 and the arc between them.  The parent and child can
 be existing nodes or nodes created by the action.
       	Place mouse cursor at the location of parent.
 press left mouse button and hold. Drag mouse to the
 location of the child and release the mouse button.

-Move Node: 
	Move an existing node to a new location.
       	Place mouse cursor at the location of the node.
 Press left mouse button and hold. Drag mouse to the
 new location of the node and release the mouse button.
  
-Del Node: 
	Delete a node and links incident to it.  Set
 prob tables of its children to default. 
       	Place mouse cursor at the location of the node.
 Press and release left mouse button.

-Del Arc: 
	Delete an arc. Set prob table of the child node
 affected to default. 
       	Place mouse cursor on the arc.  Press and release 
 left mouse button.

-Del Net:
	Delete the current net.  To be performed before
 drawing or loading a new net.

-Defn Var:
	Define the domain of a variable, or examine the 
 domain without changing it.
        To define the domain, click this button and then 
 a target node.  When a window pops up, type in cardinality 
 of the domain. Individual domain values can be specified 
 in two ways.
	1) If domain values are cells of identical width
 over a numerical interval, specify bounds of the interval
 and click Done.  A second window will pop up, where each
 cell is labeled by its lower bound.   Edit the labels as
 needed.
	2) If the domain is catergorical, do not fill the
 interval bounds and click Done.  When a second window pops 
 up, type in label of each value.

-Set Prob:
   	Define the conditional probability table of a 
 variable or examine it.
	Click this button and then a target node.  A table
 will pop up, where a "m" expression code is shown for each
 parent configuration.  Click Done and a seond table will 
 pop up.  Tab to each numberical cell and fill in the 
 probability value.
	
-Index:
	To reduce the index of node to zero.  
	If you click nodes x, y and z in sequence, their 
 indexes will become x (2), y (1) and z (0).

-Set Arrow:
	Change the size of arc arrow.  
	Clicking this button will change the arrow size to
 the next size among six alternatives.

-Arrange: 
	Clicking this button rearranges the display of the 
 net to fit the current window frame.

-Load:
	Load an existing net stored as a .bn file.
	Use the dialog window to select dir /datapub and
 then open the target .bn file.

-Save: 
	Save the current net as a .bn file.
	Use the dialog window to select dir /datapub and
 then type or select the target .bn file name.
