The model contains one compartment called C. There are three species called S1, S2 and S3 and one parameter called k1. The model contains one reaction defined as:
Reaction | Rate |
S1 → S2 | k1 · S1 · C |
The model contains one rule:
Type | Variable | Formula |
Rate | S3 | 0.15 |
The model contains one event that assigns a value to species S2:
Trigger | Delay | Assignments | |
Event1 | S1 < 0.1 | − | S2 = 1 |
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | 1.5 | mole |
Initial amount of S2 | 0 | mole |
Initial amount of S3 | 0 | mole |
Value of parameter k1 | 1.5 | second-1 |
Volume of compartment C | 1 | litre |
The species values are given as amounts of substance to make it easier to use the model in a discrete stochastic simulator, but (as per usual SBML principles) their symbols represent their values in concentration units where they appear in expressions.
