doubleFluxDel: Double Flux Deletion Experiment

Description

Double reaction (flux) deletion analysis.

Usage

doubleFluxDel(model, react1, react2, allComb = FALSE, exex = FALSE, ...)

Arguments

model

An object of class modelorg.

react1

An object of class reactId or character or integer, fluxes set to zero (upper and lower bound) (default: react_id(model)).

react2

An object of class reactId or character or integer, fluxes set to zero (upper and lower bound) (default: react_id(model)).

allComb

Logical: If set to TRUE, all possible pairwise combinations of react1 and react2 were deleted. If set to FALSE, react1 and react2 must have the same length. Every pair c(react1[i], react2[i]) will be deleted (default: FALSE).

exex

Logical: exclude exchange reactions (default: FALSE).

...

Further arguments passed to optimizer.

Value

• An object of class optsol_fluxdel.

Details

The function doubleFluxDel studies the effect of deletion of pairs of fluxes on the current objective function (e.g. biomass production). The first step is the calculation of a reference solution, which is the wild type solution. Then n further optimizations are performed (n: number of required optimizations) with $v_i = 0$ for $i = 1,\dots,n$.
