Now this is the Mersenne Twister, that is more stable, longer period and faster than the old one (JamesRandom). Unfortunately people who changed this stuff forgot to update the gjs program. So the gjs program still products JamesRandom seed files, and those files are ignored by the Mersenne Twister generator ... That is why you always get the default seed value (fixed in CLHEP) and the same results for all splited macros. To fix it: In the main program, Gate.cc file, there are few lines at the beginning of the main concerning the random generator: // // random engine //   //CLHEP::HepJamesRandom randomEngine;   //CLHEP::Ranlux64Engine randomEngine;     CLHEP::MTwistEngine randomEngine;     CLHEP::HepRandom::setTheEngine(&randomEngine); So just comment the line concerning the Mersenne Twister and uncomment the line concerning the JamesRandom engine, and recompile: // // random engine //   CLHEP::HepJamesRandom randomEngine;   //CLHEP::Ranlux64Engine randomEngine;   //CLHEP::MTwistEngine randomEngine;     CLHEP::HepRandom::setTheEngine(&randomEngine); So you will use the old generator but it will work with the gjs random seed files... And don't worry, this is fixed for the next version and new macro commands to control everything concerning the random generators will be provided (type of generator, automatic randomized seed, fixed seed, use of seed files, etc...). Coming soon.

Everything of Gate works fine...but the split jobs generated SAME results... I checked the seed-files...Initial Seed were same...9876... I took a look into the source files of Gate and tried to put one more randomization step at the initial seeds...I couldn't...
