From gwatts@phys.washington.edu Thu Apr 29 16:20:57 2004 Date: Tue, 06 Apr 2004 12:04:58 -0700 From: Gordon Watts To: Dugan ONeil Cc: greenlee@fnal.gov, Serban PROTOPOPESCU , Yaroslav Kulik , deliot@hep.saclay.cea.fr, Yann Coadou Subject: RE: Trigger info and the data format working group Hi Dugan, Ok -- that sounds great. I think the thing to do is for Yann and I to look at the code as we get a little further in. We can then figure out what, if any, modifications are required. It may be only that one has to re-write the infrastructure around the root generator, which should be pretty darn easy. Cheers, Gordon. -----Original Message----- From: Dugan ONeil [mailto:dugan_oneil@sfu.ca] Sent: Tuesday, April 06, 2004 11:21 AM To: Gordon Watts Cc: greenlee@fnal.gov; Serban PROTOPOPESCU; Yaroslav Kulik; deliot@hep.saclay.cea.fr; Yann Coadou Subject: RE: Trigger info and the data format working group Hi Gordon, OK. We did look at the code in TMBTree before starting. The reason that we didn't just add things to TMBTrees is because it was not THE D0 standard format at the time (wouldn't want it to go away from underneath us). A lot of the work that Yann has put in has been to fill out the info.....he has added many classes for different L3 objects for example. He says that most of what he has done he could translate to TMBTree-style with just some tedious changes to how the classes are fed. The ROOT macros should require very little modification. As long as Yann and Gordon stay in touch I think we can take good care of the trigger content of the TMBTree. We will still complete the work on trigsimcert for p17 so you should see an announcement of its existence (+ features) soon. Thanks, Dugan.
