This collection of model simulations/apps covers within-host and immune response modeling from a dynamical systems perspective. The software is meant to provide you with a "learning by doing" approach. You will likely learn best and fastest by using this software as part of a course on the topic, taught by a knowledgable instructor who can provide any needed background information and help if you get stuck. Alternatively, you should be able to self-learn and obtain the needed background information by going through the materials listed in the "Further Information" section of the apps.
The main way of using the simulations is through this graphical interface. You can also access the simulations directly. This requires a bit of R coding but gives you many more options of things you can try. See the
package vignette/tutorial
or the Further Information section of the apps for more on that.
The simulations are ordered in a sequence that makes sense for learning the material, so if you are completely new to this, it is best to go in order (each section top to bottom, within each section left to right). Some simulations also build on earlier ones.
