Root: An OO Framework for Large Scale Data Analysis

[0] News

Apr 20, 1998: Version 2.00/05 for MkLinux became available. I started using it and found it great. If you know PAW in CERNLIB, it's just like PAW but the command line language is C++! It has a built-in C++ interpreter and executes the standard input, line by line, as a C++ program. You can thus interactively build your analysis program in C++ and later submit it as a batch job.
You can edit resultant plots by your mouse: you can change line-, fill-, and text-attributes at will, and create colorful nice figures quite easily in encapsulated postscript format.
The ROOT is, however, more than a plotting application. You can build various data handling applications based on the ROOT libraries. Why don't you visit the ROOT home page.
The ROOT Home Page is located at

http://root.cern.ch/
from where you can get an MkLinux binary package. The ROOT system is free for noncommercial use unlike CERNLIB.

[2] How to Install ROOT

It's just expanding a tarball:

# tar -zxvf root_v2.00.MkLinux.2.1.24.tar.gz -C /usr/local

[3] Getting Started with ROOT

First thing you should do is go through the README file:

$ less /usr/local/root/AA_README

Then do

$ export ROOTSYS=/usr/local/root

$ export PATH=$PATH:$ROOTSYS/bin

You can put them into your .bash_profile or .bashrc. You should also tell the system where to find the ROOT shared libraries:

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib

or you can add /usr/local/root/lib to /etc/ld.so.conf and do "ldconfig".

Then you can try out a ROOT interactive session:

$ cd <somewhere>/

$ cp -R $ROOTSYS/tutorials .

$ cd tutorials

$ ./root
