First we run main macro file for 20 particles and stored output in PhS_new.root file. We got particle's properties(location and energy) in root with Scan command and then we closed root to make sure root will not remember the first output file due to the same tree's name. We run main macro second time with same particle number(20) to get second output file which called PhS_try.root. In root with scan we obtained particle's properties again for second run. After that we compared two text files which include particle's location and energies and there was no difference between them. </div><div dir="ltr" id="yui_3_16_0_1_1454316001163_13053"><br></div><div dir="ltr" id="yui_3_16_0_1_1454316001163_13053">David Boersma run same macro file in his computer which has Geant4 compiled with multithread OFF, and he obtained different results for same number of primaries.
