Hi All, I am trying to execute example Macros in the example like the PET_Ecat_System.mac and PET_CylindricalPET_System.mac and when I execute them the gate keep aborting it. I dont know whats the problem. Because my main macro benchmarkPET.mac runs very well. If any one has any idea what could be wrong  Thank You, Ruchir Bhatt
