For a more detailed presentation, see ODEion - a software tool for structural identification of ordinary differential equations (2013). Use this as the official reference to ODEion.
For running ODEion, see the ODEion User Guide.
The implementation of ODEion is based on Gennemark P. and Wedelin D. (2007): Efficient algorithms for ordinary differential equation model identification of biological systems IET Syst Biol. 1(2):120-9. (Submitted manuscript and supplement).
