I have compared the result between GATE4 and GATE6. In each mac file, I set
the same camera, the same phantom, the same source and activity, all the
same digitizer parameters and the same simulation time. Almost all setting
are same except the physics part due to the version. I recorded the result:
time cost: 5min 6min (longer than GATE4)
Hits.dat(size): 36MB 84MB
Singles.dat: 20MB 17MB
Coincidences.dat: 2.9MB 1.3MB
The size of the GATE6's hits.dat is larger than GATE4's. I think it's
because there are more physics process recorded in GATE6. Now what I don't
understand is that why the size of GATE6's singles.dat/coincidences.dat is
smaller than GATE4's. I checked the information in the .dat file. I found
there are singles coming from 'CylindericalPET_P', 'Phantom_P' and 'Septa_P'
in GATE4 while singles in GATE6 are only come from 'Phantom_P' and
'Septa_P'. Then what 'CylindericalPET_P' means? Who knows?
PS. I have phantom and septa attached phantomSD in each mac file. I don't
have CylindericalPET attached phantomSD in each mac file.
Thanks in advanced.
