Thank you very much.
my source is placed at 0 0 100 cm
the waterbox is placed at 0 0 -20 cm
and   i want to calculate the profil to 1.5 cm depth in water
the code become:
  /gate/actor/addActor                          DoseActor  doseprofile
> /gate/actor/doseprofile/save                  output/electron-profile.txt
> /gate/actor/doseprofile/attachTo                waterbox
> /gate/actor/doseprofile/stepHitType           random
/gate/actor/doseprofile/setPosition           0 0 -18.5 cm
/gate/actor/doseprofile/setSize               40 1 1 cm
/gate/actor/doseprofile/setVoxelSize           0.4 1 1 cm

Am I right?
