Do the example given in the table below and run the simulation in which you progressively change a single variable will keeping the others at a fixed value. The result for each trial will be the number of microtubules and the average length value. These are estimated from the screen read-out.

When doing this you should reduce the simulation time acceleration to 5 x real-time. To record the results for the desired set-up wait until the simulation has reached a steady state (the steady-state is when the simulation has passed the initial expansion phase and reached a more steady equilibrium phase) and then record the output for 5 consecutive minutes at the 0-time point.

Do this systematically for each of the 8 variables in turn following the layout in the table below (make your own copies of this!). Start by varying only 1 parameter ~ but after establishing the effect of a single parameter you may wish to try combinations. When varying a parameter do this in a series of regular steps, you can then plot the results on a graph.
