Learning ROOT

ROOT is CERN's wonderful new OO replacement for PAW. Unfortunately, it is non-trival to learn, even for experienced PAW users. It does allow interactive manipulation of histograms with a mouse-driven GUI's (adding text, fitting, etc) which is something that PAW does not do at all, but to accomplish the same manipulation via command line/scripts is MUCH more tedious than PAW (for example ROOT commands are long, non-intuitive (compared to the highly intutive PAW commands (sic), case-sensitive, and require detailed knowledge ROOT's OO classes. It is not very easy to give simple PAW-to-ROOT command conversions (though there is a one listed below). My advice, from bitter experience, is to go through Fermilab's tutorials to learn the rudiments. I think these tutorials are easier to follow than the ROOT User's Guide for a beginner. Here are some useful links:

ROOT Home page at CERN.
Old ROOT homepage at CERN. This has not been updated since 1998 and so may be useless.
Fermilab's ROOT page and tutorials: Getting Started and ROOT 101. and ROOT 102.
BeBar''s ROOT page.
Ed's PAW-to-ROOT Rosetta stone. This was compiled from other people's lists. One should not get the impression that there are always simple command conversions, however.
