Hi, Which parameter file are you editing? If it is the one INSIDE the simulation output directory, then this will not work, because this is never read, only written. Are you using simfactory? If so, then I usually just edit the parameter file in <simulation>/SIMFACTORY/par then submit the next segment. -- Ian Hinder http://members.aei.mpg.de/ianhin
