The model contains one compartment called C. There are two species called S1 and S2 and one parameter called k1. The model contains one reaction defined as:
Reaction | Rate |
S1 → S2 | C · k1 · S1 |
The model contains one rule which assigns value to parameter k1:
Type | Variable | Formula |
Assignment | k1 | 0.75 |
In this case there is no initial value declared for parameter k1. Thus the value must be calculated using the assignmentRule.
The model contains one initialAssignment:
Variable | Formula |
S1 | k17.5 |
Note: InitialAssignments override any declared initial values. The initial value of species S1 is undeclared and so must be calculated by the initialAssignment.
The initial conditions are as follows:
Value | Units | |
Initial amount of S1 | undeclared | mole |
Initial amount of S2 | 0.15 | mole |
Value of parameter k1 | undeclared | second-1 |
Volume of compartment C | 2.5 | 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.
