Dear LCD colleague, Although it is a develop version, new RootApps, simulation and analysis tools based on ROOT, is available at SLAC. The tar.gzip file can be obtained from /afs/slac.stanford.edu/public/groups/lcd/RootApps/dev/RootApps-dev.tar.gz or from FTP ftp://ftp.slac.stanford.edu/groups/lcd/RootApps/dev/ The file include Marty's new detector parameter file, Silicon.par and corresponding tracker smear parameter lookup_silicon.* by Bruce. It has also the Precise detector parameter file, but doesn't have the tracker smearing parameter for this detector yet. The dev version RootApps is good for FastMC, but we are still working for FullMC. The main new features are * Neural Network output for b/c separation in ZVTOP output; Neural Network is used for track attachment in ZVTOP by Toshi * Bug fixed in Calorimetry position smearing * Event Display * ( can handle the SIO file ) .. still working for SunOS Many of the class definitions have been changed. Please see Web page http://www-sldnt.slac.stanford.edu/nld/New/Docs/LCD_Root/rootHtmldev/html/ClassIndex.html which is linked from http://www-sldnt.slac.stanford.edu/nld/New/Docs/LCD_Root/root.htm For this dev version, please use Root version 3.00/** or later. We also install the dev version files in /afs/slac/g/nld/RootApps for SLAC users. To use them 1) Copy rootrc_example as .rootrc in your space 2) Modify your .cshrc ... add the lines in cshrc_example The rootrc_example and cshrc_example files are in /afs/slac/g/nld/RootApps/dev/Examples The directory also contains some analysis example files. - Masako
