[Gate-users] Crashing with a detector nested in a vox phantom

[David Sarrut]

Hello Francisco,

does it works if the volumes do not overlap ? Try step by step:
- simulation with vox + source outside the volume (check everything is ok)
- simulation with vox + source inside the volume (check everything is ok)
- simulation with vox + ouside source + outside spect system (check
everything is ok)
- end with your final goal

btw, I recommend to use mhd file format rather than hdr (see wiki).

David
