 In order to calculate the circuit signal, once the node activity values have been estimated, we assume an incoming signal value of 1 in the input nodes (stimuli-receptor proteins) of any circuit. Then, the signal is propagated to the following nodes as shown in the image above until it reaches its effector node. This is going to be the values that will be taken as the activation value for each "effector circuit". In order to calculate the circuit signal, once the node activity values have been estimated, we assume an incoming signal value of 1 in the input nodes (stimuli-receptor proteins) of any circuit.

-In the  +Finally, Hipathia also calculates the activation state of some molecular functions by looking at the functions annotated for the effector proteins in which the "effector circuit" finishes. With Hipathia's method it is possible to obtain an individual activation value of the different functions for each. Therefore it's also possible to infer which functions have different activation levels in the groups that are being compared. This feature is implemented for the annotations of the Uniprot database and Gene Ontology.

 This module offers an interactive working environment to simulate the effect of different interventions (e.g. knock-out, over-expression, etc.) over the activity of signaling circuits in the pathways, as well as their potential functional consequences in the cell. Given a specific condition, corresponding to a specific gene expression profile, knock-outs, knock-downs or different types of inhibitions are simulated by reducing or setting to 0 the expression level of the gene or interest.  This module offers an interactive working environment to simulate the effect of different interventions (e.g. knock-out, over-expression, etc.) over the activity of signaling circuits in the pathways, as well as their potential functional consequences in the cell.
