The model contains one compartment called "compartment". There are two species named S1 and S2 and two parameters named k1 and k2. The model contains one reaction defined as:
Reaction | Rate |
S1 → S2 | compartment · k2 · S |
The model contains one initialAssignment:
Variable | Formula |
S1 | k1 · S2 |
Note: SBML's InitialAssignment construct override any declared initial values. In this model, the initial value for the species S1 has not been explicitly declared and must be calculated using the InitialAssignment.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | undeclared | mole |
Initial amount of S2 | 1.5 × 10−2 | mole |
Value of parameter k1 | 0.75 | dimensionless |
Value of parameter k2 | 50 | second-1 |
Volume of compartment "compartment" | 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.
Note: The test data for this model was generated from an analytical solution of the system of equations.
