Thanks. If we don't get in touch with you soon enough pester me again. I don't know how this is going to work out, but I'll try to make sure that we add it to the list of things. Cheers, Gordon. -----Original Message----- From: Dugan ONeil [mailto:dugan_oneil@sfu.ca] Sent: Monday, April 05, 2004 11:34 AM To: greenlee@fnal.gov; Serban PROTOPOPESCU; Gordon Watts; Yaroslav Kulik; deliot@hep.saclay.cea.fr Cc: Yann Coadou Subject: Trigger info and the data format working group Hi Herb, Serban, Gordon, Slava, Frederic I am very glad you have agreed to tackle the issue of a common ROOT format for D0! This is certainly needed. I wanted to make you aware that a couple of SFU people (led by Yann Coadou) have been writing tools to look at trigger output in the TMB. A standard tree is produced using some well-thought-out classes and some nice macros are provided to look at the contents (including every trigger subsystem, no more need to supply a toollist, reference distributions with chi-squared fits, etc.). While you are considering what trigger info needs to go into the new standard format I hope you will contact Yann about using (or adapting) his classes. It is better that we get the chance for input early in the process then rewrite everything from scratch. Do I understand correctly that this might be a wholesale reworking of the TMBTree (ie. it is still TMBTree in name only) or is it meant to be a small perturbation to that format? Thanks, Dugan. -- ------------------------------------------------------------------------ ---- Dugan O'Neil E-mail : dugan_oneil@sfu.ca oneil@fnal.gov Dept. of Physics phone: 604-291-5623 Simon Fraser University fax : 604-291-3592 8888 University Drive Burnaby, BC Canada, V5A 1S6 If trees could scream, would we be so cavalier about cutting them down?
