anNET

Main content

anNET affords a generalized framework for Network Embedded Thermodynamic (NET) analysis of quantitative metabolomic datasets. Building upon principles of thermodynamics, this method allows for a quality check of measured metabolite concentrations and enables to spot metabolic reactions where active regulation potentially controls metabolic flux.

The applications of anNET are multiple, for example:

  • Check thermodynamic consistency
  • Estimate unmeasured concentrations
  • Resolve concentrations in different compartments
  • Find minimum/maximum feasible NADH/NAD ratio or adenylate energy charge
  • Infer reaction direction
  • Verify reversibility in model
  • Spot putative control sites
  • Exclude activity of transporters

Requirements

Matlab 6.0 or higher (tested on Windows and Linux)
Matlab Optimization Toolbox 3 (The Mathworks) or Lindo API (Lindo Systems, Inc.)
