Hi everyone,

I tested the new master macros today. When I run sim_complete.C with a dec-file, the seed is always changed from -1 to 4357.
After I added the line
gRandom->SetSeed();

to sim_complete.C the seed is set properly Smile . It seems that this line is missing somewhere.

Cheers,
Jenny

gRandom->SetSeed() is to have a random seed each time you run a simulation. If you do not write the line, the seed is always the same.
The line has to be added only if needed.
