DEM 2 GATE - Making DEM radioactive

The simple DEM to GATE script enables the user to transform the particle data into a GATE- readable dataformat in 2 different steps.

1. Generate a Volumetric Average of all particle positions to generate the scatter region due to other particles
2. Generate a trajectory file to use one or multiple particles as tracers

The user needs to include those files in GATE. Also a lookup-table for the different Materials in the Scatter Volume must be defined.

Usage

In Ipython simply run

run base.py 
d2g = Dem2Gate("data",tracer_time = 100)
d2g.generate_data(  image_filename="volume.mhd",
                    traj_filename="gate.traj"
                 ) 

This will take all .vtk files from the data folder and generate the volumetric file.
It will be saved in image_filename -path also the tracer trajectory will be saved in
traj_filename.
The variable tracer_time helps choosing the number of particles that will be used as
a tracer. Their positions will be added to a single big trajectory. You can also manualy choose the particle ID's. Simply choose the variable tracer_id
and pass either a single ID or a list/array.

If you want to have multiple tracers you need to rerun the whole script with different
Tracer IDs. We are sorry, that's on our To-Do list!
