The error that my program returned is the following: GateSourceMgr.cc (l.258): GateSourceMgr::CheckSourceName : ERROR : source name <F18> already exists Can you help me? how many times to define sources F-18? One for each sphere? i.e., Four sources? </div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:small"> The part of my code referred to particle sources is this: #============================================================ #
