sybilcycleFreeFlux (version 2.0.2)

llFBA: looplessFBA

Description

implements loopless FBA as described in Schellenberger et al 2011 algorithm.

Usage

llFBA(model, lpdir = SYBIL_SETTINGS("OPT_DIRECTION"), solver = SYBIL_SETTINGS("SOLVER"),
   method = SYBIL_SETTINGS("METHOD"), solverParm = data.frame(CPX_PARAM_EPRHS = 1e-07),
  verboseMode = 2)

Arguments

model

An object of class modelorg.

lpdir

Character value, direction of optimisation. Can be set to "min" or "max". Default: SYBIL_SETTINGS("OPT_DIRECTION").

solver

Single character value. The solver to use. See SYBIL_SETTINGS for possible values. Default: SYBIL_SETTINGS("SOLVER").

method

Single character value. The optimization algorithm to use. Possible values depend on the setting in solver. See SYBIL_SETTINGS for possible values. Default: LP_METHOD(SYBIL_SETTINGS).

solverParm

additional parameters to the solver

verboseMode

level of output messages

Value

status returned from the solver, objective value, and the fluxes returned from solver.
