Deterministic and Stochastic Simulations
To study our model, we decided to run two type of simulations. First of all, we have started with deterministic simulation in order to see whether our description of the chemical cascade reflected our understanding and expected behaviour of the reception system. Then, to check whether our system was sensible to molecular noise, we decided to run exact stochastic simulations based on the Gillespie method.
Deterministic Model
We used classical algorithms to solve the system of differential equations and get deterministic simulations ;
Stochastic Simulations
Several runs of stochastic simulations were run for the different values of k and the different initial amounts of FecA. We used a Gillespie algorithm to compute the amounts of molecules at each step ; the simulations were run with Matlab Simbiology toolbox.
