[Gate-users] Voxelized source placement

Dear Coleagues,
I am having some trouble to correctly position the voxelized source (or
to define its size??). Somehow, no matter what I do to the Interfile
(float, unsigned integer, ...), or where I shift it, only half of it is
present in the simulation. I attached an image of a simulation
(generated e- are displayed in red) and the original Interfile. The mhd
file of the source can be found by following the link:
https://www.dropbox.com/sh/jttacutgwo3hn4s/AADfPsa0X_7FiPLp3fSwkHSLa?dl=0
I use the following code to read the source:
/gate/source/addSource source_PET voxel
/gate/source/source_PET/reader/insert interfile
/gate/source/source_PET/interfileReader/translator/insert range
/gate/source/source_PET/interfileReader/rangeTranslator/readTable
act_range_file_complete_phant.dat
/gate/source/source_PET/interfileReader/rangeTranslator/describe 1
/gate/source/source_PET/interfileReader/readFile
data/phantom/NEMA_phant_PET_staphan.h33
/gate/source/source_PET/setPosition -342.132 -342.132 0 mm
# e- source for testing
/gate/source/source_PET/gps/particle e-
/gate/source/source_PET/setForcedUnstableFlag true
/gate/source/source_PET/setForcedHalfLife 1 ms
/gate/source/source_PET/gps/energytype Mono
/gate/source/source_PET/gps/monoenergy 30.00 keV
I honestly ran out of ideas what I could be doing wrong. Any help would
be great.
Thanks in advance and cheers,
Albert
