mod2irrev: Produces a Model in Irreversible Format

Description

The function mod2irrev produces a model with all reactions moving in positive direction.

Usage

mod2irrev(model, exex = FALSE)

Arguments

model

An object of class modelorg.

exex

boolean. Exclude exchange fluxes (default: FALSE).

Value

• An object of class modelorg_irrev.

encoding

utf8

Details

The returned model consists only of reactions moving in positive direction. Reactions with a negative direction in the original model are transferred to positive direction; the corresponding reaction id gets extended by _r.

Reversible reactions are split into two reactions. The corresponding reaction ids gets extended by _f, or _b indicating the original direction.

If exex = TRUE, the exchange reactions were obtained by findExchReact.
