Hi, I am generating e-e+ events with fixed momenta (px=0, py = 0.04, pz= 1.05) GeV, for e+ only py is -0.04 GeV. Then with standard procedure I am trying to get dst files: slic->hps(readout)->hps(recon)->dst_maker from generated 225 events I got only 174 in recon and 121 in dst, and from that 121 only 3 events contained 1 track, all others didn't have any track in it. My expectation was that I should be able to get almost all generated events, since they all are within HPS acceptance (see this figure from one particular event) https://userweb.jlab.org/~rafopar/HPS/gen_recon/em_ep_Wired_View.gif Kyle provided me a trigger driver Alltrigger.java, which accepts all events, and readout was done using that driver along with TestRunTriggeredReconToLcio (https://userweb.jlab.org/~rafopar/HPS/gen_recon/AllTrigger.java) so it shouldn't be a trigger effect. I am not sure where I am doing mistake(s). I would appreciate any comments, suggestions. In case if some additional information is need, I put files in the following directory File names are self explanatory https://userweb.jlab.org/~rafopar/HPS/gen_recon/ Rafo ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
