Installation requirements

The code uses Python 2.7+.

A number of standard scientific python packages are needed for the numerical simulations and visualizations. An easy way to install all of these is to install a Python distribution such as Anaconda.

Additionally the code also relies on these packages:

And optionally for nicer progress output install:

Running the code

The time stepping of the population dynamics is accelerated by a Cython module, which needs to be compiled first. To compile it run make cython in the lib directory. In the directories for the different figures launch make run followed by make agg to produce the underlying data. Please copy the paper.mplstyle to your custom matplotlib style directory (likely .config/matplotlib/stylelib/). We provide both Jupyter notebooks with additional explanatory comments and plain python files for generating the figures.

Remarks

In the code we use the following simplified notations c_constitutive = mu1, c_defense = mu2, c_infection = lambda_, c_uptake = cup and we define the trade-off c_defense(c_constitutive) as a parametric function of a parameter epsilon in [0, 1], where 0 corresponds to fully constitutive and 1 to maximally regulated responses.

Note: As the simulations are stochastic you generally will not get precisely equivalent plots.
