" ... We introduce a combined numerical and analytical technique that aids the identification of structure in a class of systems of nonlinear ordinary differential
equations (ODEs) that are commonly applied in dynamical models of physical processes.
These methods have been incorporated into a new software tool named Dssrt, which we demonstrate
on a limit cycle of a synaptically driven Hodgkin–Huxley neuron model."
