Peace, this is Andre at Purdue. I am running the nld_bat on a AIX machine. I have generated a hepevt file this.dat. I am looking at http://www-sldnt.slac.stanford.edu/nld/documentation/FullSim/FullSim.htm It says the command line to run it is > $LCD_DIR/nld_bat Detector.ini 'generator-name' Gen.ini 100 mydir/output.dat runNumber rndmSeed I am using the Large.ini file. However WHAT IS THE "Gen.ini" file. I have not been able to find it anywhere, and it didn't come with the package. Is there one I can use for the Large Dectector for NLC? Also are the runNumber and rndmSeed arguments optional, and if not what should I use? Thank you. Andre' [log in to unmask] http://www.physics.purdue.edu/~mac/
