You can use Netica to display information or report windows, called user reports. The purpose is mainly to provide extra information, assistance or directions either to developers or to others who may be using/viewing your BN. A user report could be as simple as a text message giving a more detailed description of a node. Or it could be more complex, such as the current belief probabilities of a node-set, or a sensitivity analysis of questions with respect to the target node.
User reports are often used with AutoNetica, as they can also be created for the user on the current case or inferred results, which can be printed out or saved to file. They can also be used from the API.
The Netica mechanism to support this is called custom reports. You can create a template file or modify an existing template (usually in HTML with special notations for report elements to be inserted) which defines what you want to have displayed. You then access that template file from your Bayes net. A template file can be used to generate a report on the overall model (i.e. Bayes net), or it can apply to individual questions (i.e. nodes). In the first case, it is called a net template file, and the tags within it start with "Net", and in the second case it is called a node template file, with tags that start with "Node".
