The influence map is a "Who activates whom" or "Who inhibits whom" diagram that shows the relationships between rules. Specifically, it illustrates the causal dependencies and influences between all the rules in the cBook. There are two types of influence maps: the syntactic and the model influence maps.

Syntactic Influence Map

The syntactic influence map shows one degree of separation (within the cBook) and is based purely on the kappa, not on the initial conditions or triggerable rules. It is automatically generated on each rule page by clicking on the Influence Map tab.

Without Inhibition                                                                                                With Inhibition

On the influence map, individual rules are shown as nodes, connected by arrows that describe their inhibitory (red) and inducible (green) relationships in the model. The influence map can be displayed with or without inhibition by using the "Show Inhibition" or "Hide Inhibition" button. When clicking on a specific rule in the influence map, a window pops up with the name and kappa string of that rule along with a link to its rule page. As more rules are added to the model, it may become difficult to read the map in the browser. The user can zoom in (+) or out (-) or choose to view the influence map at a larger scale using the "Full Screen" button. The user can leave the full screen mode by hitting the escape key (Esc) or using the "Exit Full Screen" button.

Model Influence Map

In addition to the rule page, the influence map can be generated on the model page by clicking on the influence map tab, which appears after the user adds the initial conditions and rules. The model influence map only shows rules in the model, and these rules do not have to be triggerable to appear on the map. This influence map has all the same features as mentioned above but it also has an option to change hops. Adding hops simply changes the degree of separation that the map shows for the center rule. The user can change the rule of focus by clicking on a new rule that they want to be at the center, then hitting the "Recenter" button on the pop-up window. The influence map can be used as a powerful tool to navigate the rules based on the relationships you define in the model.
