Detailed Description

Represents the Mirams et al. system of ODEs, based on Swat et al. (2004) [doi:10.1093/bioinformatics/bth110] and a simple Wnt model (unpublished)

The variables are

0. r = pRb 1. e = E2F1 2. i = CycD (inactive) 3. j = CycD (active) 4. p = pRb-p 5. c = destruction complex (Active) 6. b1 = Beta-Catenin (from 1st allele) 7. b2 = Beta-Catenin (from 1st allele) 8. WntLevel

Constructor & Destructor Documentation

WntCellCycleOdeSystem::WntCellCycleOdeSystem	(	double	WntStimulus = `0.0`,
		boost::shared_ptr< AbstractCellMutationState >	pMutationState = `boost::shared_ptr<AbstractCellMutationState>()`
	)

Constructor.

Parameters:

	WntStimulus	is a non-dimensional Wnt value between 0 and 1. This sets up the Wnt pathway in its steady state.
	pMutationState	affects the ODE system

State variables.

0. r = pRb 1. e = E2F1 (This is the S-phase indicator) 2. i = CycD (inactive) 3. j = CycD (active) 4. p = pRb-p 5. c = APC (Active) 6. b1 = Beta-Catenin (1st allele's copy) 7. b2 = Beta-Catenin (2nd allele's copy) 8. wntLevel

Member Function Documentation

double WntCellCycleOdeSystem::CalculateRootFunction	(	double	time,
		const std::vector< double > &	rY
	)			`[virtual]`

When using CVODE this function is called instead of CalculateStoppingEvent. It allows the point at which rY[1] reaches 1 to be found to greater precision.

Parameters:

	time	at which to calculate whether the stopping event has occurred
	rY	value of the solution vector used to evaluate the RHS

Returns:: function value - giving CVODE an estimate of how close we are to the root.

Reimplemented from AbstractOdeSystem.

Definition at line 286 of file WntCellCycleOdeSystem.cpp.

bool WntCellCycleOdeSystem::CalculateStoppingEvent	(	double	time,
		const std::vector< double > &	rY
	)			`[virtual]`

This also contains a calculation of dY[1], copied from EvaluateYDerivatives. Ensure they do not get out of sync!

Parameters:

	time	at which to calculate whether the stopping event has occurred
	rY	value of the solution vector used to evaluate the RHS

Returns:: whether we have reached the stopping event

Reimplemented from AbstractOdeSystem.

void WntCellCycleOdeSystem::EvaluateYDerivatives	(	double	time,
		const std::vector< double > &	rY,
		std::vector< double > &	rDY
	)			`[virtual]`

Compute the RHS of the WntCellCycle system of ODEs.

Returns a vector representing the RHS of the ODEs at each time step, y' = [y1' ... yn']. An ODE solver will call this function repeatedly to solve for y = [y1 ... yn].

Parameters:

	time	used to evaluate the RHS.
	rY	value of the solution vector used to evaluate the RHS.
	rDY	filled in with the resulting derivatives (using Alarcons et al. (2004) system of equations).

Implements AbstractOdeSystem.
