SimBiology® lets you find species, parameters, and compartments that are not used in a model. You can also query how a particular quantity is used by other expressions such as a parameter being used as a reaction rate constant or species being used in an event.
From the command line, use the findUnusedComponents function to look for unused model components and
the findUsages function to see how a
component is used in expressions. If you are using the SimBiology Model Builder app, in the
Browser pane, expand Model Assessment
Tools. Then click Unused to see a list of unused
quantities. To look for usages of a quantity, click the quantity block in the diagram or
in the browser table. Then in the Property Editor pane, look at the
Usages section.
A species is used when it is referenced in any of the following properties of other components:
The Reaction or ReactionRate property of a
Reaction object,
The ParameterVariableNames or
SpeciesVariableNames
property of a KineticLaw object,
The Rule property of a
Rule object,
The Trigger or EventFcns property of an
Event object,
The Expression property of an observable object, and
The TargetName property of a
ScheduleDose object or
RepeatDose object.
A parameter is used when it is referenced in any of the following properties of other components:
The ReactionRate property of a
Reaction object,
The ParameterVariableNames
property of a KineticLaw object,
The Rule property of a
Rule object,
The Trigger or EventFcns property of an
Event object,
The Expression property of an observable object,
The Content property of a
Variant object, and
The DurationParameterName or LagParameterName property of a ScheduleDose object or
RepeatDose object.
The Amount, Rate, Interval, StartTime, or RepeatCount property of a
RepeatDose object.
A compartment is used when it is referenced in any of the following properties of other components:
The Parent property of a
Species object,
The Owner property of a
Compartment object,
The ReactionRate property of a
Reaction object,
The ParameterVariableNames
property of a KineticLaw object,
The Rule property of a
Rule object,
The Trigger or EventFcns property of an
Event object,
The Expression property of an observable object, and
The Content property of a
Variant object.
An observable object is used when it is referenced in the
Expression property of another observable.
A unit or unit prefix is used when it is referenced in any of the following properties of other components:
The Composition property of all
units in the BuiltInLibrary and
UserDefinedLibrary,
The Units
property of a species, compartment, parameter, or observable object in the
specified models,
The TimeUnits property of all
specified doses,
The AmountUnits property of all
specified doses, and
The RateUnits property of all
specified doses.
An abstract kinetic law object aklObj can only be used by a
Reaction object
robj. It is used when:
The KineticLaw property of the
reaction object is not empty, and
robj.KineticLaw.KineticLawName matches the name of the
abstract kinetic law aklObj.Name.
