Hi Takashi, I’m not seeing the same by just counting events with no trigger bits set according to the DST variables. For example, this returns zero for the file you mentioned and a few others I tried: HPS_Event->GetEntries("pair1_trigger+pair0_trigger+pulser_trigger+single0_trigger+single1_trigger == 0”) -Nathan On Jul 7, 2015, at 13:06, Maruyama, Takashi <[log in to unmask]> wrote: > There is a minor problem in trigger bits in pass1 DST. There are about 7% of events with no trigger bits set. There are about 2% of events with both Single0 and Single1. Kyle dumped first 1000 EVIO events in Run 5797 File 0, and I compared with the DST.
