Flux variability analysis

FVA class

Performs flux variability analysis. It is based on the paper of (Gudmundsson and Thiele, Bioinformatics 2010).

Configuration

biomass_optimization

Optional

Biomass optimization

Type : stringAllowed values :   maximize  minimize 

fluxes_to_maximize

OptionalAdvanced parameter

The fluxes to maximize

Type : list

fluxes_to_minimize

OptionalAdvanced parameter

The fluxes to minimize

Type : list

solver

OptionalAdvanced parameter

The optimization solver. It is recommended to use `quad`. Other solvers are in `beta` versions.

Type : stringAllowed values : quad  highs-ds  highs-ipm  highs  interior-point  Default value : quad

relax_qssa

OptionalAdvanced parameter

True to relaxing the quasi-steady state assumption (QSSA) constrain (`quad` solver is used). False otherwise.

Type : bool

qssa_relaxation_strength

OptionalAdvanced parameter

Used only if the QSSA is relaxed. The higher is the strength, the stronger is the QSSA. Hint: Set to the number of reactions to have strong QSSA contrain.

Type : float

parsimony_strength

OptionalAdvanced parameter

Set True to perform parsimonious FBA (pFBA). In this case the quad solver is used. Set False otherwise

Type : float
