But I know for sure that if I do not use digigate and run one simulation for any change of value in the deadtime I get different values for Prompts, Trues, Random and Scatter events, as I expect to have. </FONT></DIV> <DIV><FONT face=Tahoma size=2></FONT> </DIV> <DIV><FONT face=Tahoma size=2>Has anybody any idea ?
