Figure 3From: Visual setup of logical models of signaling and regulatory networks with ProMoTIllustration of the setting of parameters by the encoding of multiple levels. Properties like the multilevel variable can be edited in the variable editor. The parameter a (level of activation) default equals 1, and can be modified to encode multilevel logical operations. For example, in the toy model (see Figure 2), tf1 reaches a level 2 if both k3p1 and k3p2 are active. This is set up in ProMoT via a gate of the class AND where the output has a = 2).Back to article page
