Additional file 4:

Perturbation protocol. Example of perturbation protocol file used to perform the simulations. The file describes two perturbations. The first one on the Th0 state with IL-4, the second on the Th0 state with IL-4 and subsequent IFN-γ addition. The file can be loaded from the Perturbation tool in SQUAD. The file also contains three different perturbations of the IL-18 node aimed at demonstrating the use of the different pulse types: "constant", "range" and "single".
