[Gate-users] Did not understand the command /gate/volume1/surfaces/surface1/setSurfacename surfacename

If you define the surface between your PMT(cylinder) and the SPECThead as
your detecting surface, you
need to do the following:

Definition of the surface going from specthead (Sensitive detector volume)
towards pmt:

/gate/SPECThead/surfaces/name                           Detection
/gate/SPECThead/surfaces/insert                           pmt

(Your entire SPECThead is your sensitive detector? You did not define any
crystal or pixel levels?*)*


You can also define the surface going from your pmt towards spect_head
which is not the same as
the previous surface.

Let me know how it goes.
