Dear Gate users,
I'm trying to use the mouse phantom from [ https://neuroimage.usc.edu/neuro/Digimouse_Download | https://neuroimage.usc.edu/neuro/Digimouse_Download ] .
So I have my phantom of the form mouse.hdr , mouse.img and here is my code:
1. I name my phantom, open the file and choose the algorithm to track particles from voxel to voxel
2. I convert my image grayscales into material definitions with an units to materials conversion descriptor
/gate/HounsfieldMaterialGenerator/SetDensityTolerance 0.1 g/cm3
I get the following error message
GateVImageVolume.cc (l.739): I find R=0 in the image, while range stop at -1
### WARNING ### setSkipEqualMaterials at false !! The Geant4 method is not safe since the release 9.5 - Need to be fixed
Error opening file.
Does someone has an idea how to solve this problem ?
Thank you in advance for your help,
