Attempt to find multiplicative reaction rate coefficients

This function assumes that the kinetic Law is mass action kinetics. This function helps in converting the units of an ODE into units that work in stochastic simulations. Converting the units of a general formula (Michaelis Menten, Hill kinetics, etc.) is difficult and dubious in stochastic simulations.

Usage

parameter.from.kinetic.law(kineticLaw, tab)

Arguments

kineticLaw

a string with a mathematical formula

tab

an SBtab document, as returned by SBtabVFGEN::sbtab_from_tsv()

Value

a parameter with value, and unit as attribute

Details

For these reasons, this functions assumes: kf*A*B*[...] with the first word kf representing the reaction rate coefficient.

Given an SBtab document, this function finds the value (if any) and unit of this coefficient. The coefficient itself can be defined as a fixed constant, a parameter, or an algebraic expression in the document. The most important attribute here is the unit.
