Description

This function integrates the sampled seahorse measurements as constraints into the specified model, optionally maximizes an objective reaction, minimizes total flux for each sample, and returns a matrix of reactions-by-samples where the entries are predicted fluxes.

fluxPredict(model, seahorse_data, biomass_est = 0, alg = c("mtf", "fba"),
  low.wt.rxns = NULL, obj_rxn = NULL, model.nm = "2.1A",
  solver = c("gurobi", "glpk"))

Arguments

model

An object of class modelorg.

seahorse_data

A data.frame returned by map_seahorse

biomass_est

Estimated biomass flux. Default = 0.

alg

Either "fba" (default) to optimize a reaction or "mtf" to only minimize total flux (and not do fba).

obj_rxn

Reaction in model to optimize if alg="fba". Default NULL optimizes ATP demand reaction.

model.nm

The metabolic model name. One of "2.1A", "2.1x", or "2.2".

solver

The solver to use; "gurobi" (default) or "glpk".

Details

For parallel computing, a parallel backend must be registered. See foreach for details.
