In the first step, the BN we want to run should be uploaded in the .dne or .net format (as created in Netica or another BN software). This is done by using “choose file” and selecting the network file, or dragging and dropping the network file into the application. Then, we click “Proceed”.

Once a network has been uploaded, it is visualized in the GUI, displaying the nodes with their states (in case of continuous nodes, the upper bound of each interval is displayed), and the links between them. The nodes can be moved around.

When hovering with your mouse above a node, additional options appear. A node can be selected as a target node, which means that the output of running the network will contain the posterior probability distribution of this node. When we select a node as a target node, a target icon will appear in its upper right corner. You may want to save the configuration of the run (includSing the information about which are the target nodes, etc.), in case you will run it again later. You can also upload a previously saved configuration.

By clicking on the state of a node, we set that state as hard evidence, which is then shown in bold. This is useful for non-spatial evidences, for nodes which have the same state over the whole study area, such as an agricultural policy.
