====== Documentation ======
In this page you find the reference paper for DigR, some academic presentations to explain root architecture, DigR model, DigR use into Xplo environment and some training sessions.

List of presentations about root systems Architecture, Observations, Modelling, Simulation and Exploration.

You can download them to get every informations about root-systems architecture, growth and development modelling,  DigR model and AMAPstudio software environment. 

In each presentation, we introduce parameters which are used to model 3D root-system architecture.
  * The values of parameters are then saved in a parameter file.
  * This parameter file will be used by DigR simulator in Xplo sofware to build a 3D root-system mockup
  * See Parameter Files section to get theses parameter files.


For each parameter of DigR model described in the presentations, we detail its meaning and how to use it.

//**NOTE : if you want to download these files, do "right click" with mouse. By default, they will be opened in a new window (pdf format).**//
