The dnaphysics example shows how to simulate track structures in liquid water
using the Geant4-DNA physics processes and models.
This example is provided by the Geant4-DNA collaboration.
These processes and models are further described at:
http://geant4-dna.org
Any report or published results obtained using the Geant4-DNA software shall
cite the following Geant4-DNA collaboration publication:

In interactive mode, run:

./dnaphysics
The macro dna.mac is executed by default. It shows how to shoot different
particle types.
To get visualization, make sure to uncomment the #/control/execute vis.mac
line in the macro.

---->4. PHYSICS
This example shows:
- how to use the Geant4-DNA processes, using the G4EmDNAPhysics constructor
(look at the PhysicsList.cc file)
- how to affect them a name
- how to affect them a number
(look at the SteppingAction.cc file)

- the type of process for the current step
- the track position of the current step (in nanometers)
- the energy deposit along the current step (in eV)
- the step length (in nm)
- the total enery loss along the current step (in eV)
This file can be easily analyzed using for example the provided ROOT macro
file plot.C; to do so :
* be sure to have ROOT installed on your machine
* be sure to be in the dnaphysics directory
* launch ROOT by typing root
* be sure to be in the directory containing the ROOT files created by dnaphysics
* copy plot.C into this directory
* from there, launch ROOT by typing root
* under your ROOT session, type in : .X plot.C to execute the macro file
* alternatively you can type directly under your session : root plot.C
The naming scheme on the displayed ROOT plots is as follows (see SteppingAction.cc):
This is the same naming scheme as in the "microdosimetry" advanced example.
