Hi, I have looked through most of run2144seq000.dat with Alv's new tpc display and I don't see any nice tracks in T2 ( All the other detectors have nice tracks ). You can find small parts of tracks (see for example evnt 2000) and "weak" tracks (see for example event 12182, and lower the minimum ADC value). If somebody has a real nice track in any resent event please write the data sequence and event number. BTW, I thought the triggerword1 had the same 2 digits in front as in the back (0101, 2121 etc ), but I sometimes see 2939, 2030, is there a reason for this ? Is anybody thinking of including clustering, tracking etc. in Alv's code ? I have looked at it and will try to include it as a clickable feature if no one else is doing / have done (please;) it.
