Dear Gate Users,
I used shep plogan phantom as a source of voxel phantom and simulation.  


question 1,   I can’t see the green gamma rays. Is my source setting wrong?


the code is 
/gate/source/addSource VoxelizedSource voxel
/gate/source/VoxelizedSource/reader/insert image


/gate/source/VoxelizedSource/imageReader/translator/insert              linear
/gate/source/VoxelizedSource/imageReader/linearTranslator/setScale      1. Bq


/gate/source/VoxelizedSource/imageReader/translator/insert range
/gate/source/VoxelizedSource/imageReader/rangeTranslator/readTable ActivityRange.dat
/gate/source/VoxelizedSource/imageReader/rangeTranslator/describe 1
/gate/source/VoxelizedSource/imageReader/readFile phantom3d.mhd
/gate/source/VoxelizedSource/imageReader/verbose 1




# THE DEFAULT POSITION OF THE VOXELIZED SOURCE IS IN THE 1ST QUARTER
# SO THE VOXELIZED SOURCE HAS TO BE SHIFTED OVER HALF ITS DIMENSION IN THE NEGATIVE˓→DIRECTION ON EACH AXIS


/gate/source/VoxelizedSource/setPosition   -128 -128 -128 mm
/gate/source/VoxelizedSource/dump 1




/gate/source/VoxelizedSource/setType backtoback
/gate/source/VoxelizedSource/gps/particle gamma
/gate/source/VoxelizedSource/gps/energytype Mono
/gate/source/VoxelizedSource/gps/monoenergy 140. keV

/gate/source/VoxelizedSource/gps/maxtheta 90. deg
/gate/source/VoxelizedSource/gps/minphi 0. deg
/gate/source/VoxelizedSource/gps/maxphi 360. deg
/gate/source/VoxelizedSource/gps/confine NULL


/gate/source/list


And ActivityRange.dat

0 0 0
0.2  0.2 1
0.3  0.3 3
1  1 5


question 2,  My detector can only be rotated 180° and then it automatically exits, and the results cannot be saved. Anyone who knows?
/gate/SPECThead/orbiting/setSpeed 5.625 deg/s
