Hi,

The VoxelTest.txt is just an example how you can specify some ‘special’ voxels where to get the dose info.

It is thought to have a quick comparison to the experimental data (the dose parameter after the x,y,z data) consequently you should decide the voxel centre (x,y,z) and its half size (dx,dy,dz) in mm. As a consequence if you set (dx,dy,dz)=(1,1,0) you will not get any relevant data (dose=0) because the volume of the voxels is 0.

Furthermore, in order to have different curves (say f.e. a PDD and a section) the number of curves as well as the starting and ending index of the data have to be specified after the token Start. The third number must exist but is not used.

For example:

Start

2

1 10 1

8 25 0

x y z dose

Indicates 2 curves, the first in the range 1-10 and the second in the range 8-25 of the sequence of voxels described after x y z dose line.

Probably in your case you should use the ROG output files.
