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.</div><div><br class=""></div></div><div class="">
