LIGOtools Package: root

This is a slightly re-packaged version of ROOT, the object-oriented data analysis and display environment developed at CERN, which is launched by typing ltroot. As a LIGOtools package, this is primarily intended for interactive use, especially with other LIGOtools packages which may provide ROOT macros and/or ROOT-enabled shared-object libraries, such as eventtool, dmtroot, Fr, and Frv. It also works as a regular version of ROOT, of course.

Frequently Asked Questions related to this package

Notes

At present, this package is available as a binary distribution for Solaris or for Intel Linux. There is also a "source" distribution, but it has only been set up to build automatically on Solaris and Linux using gcc. Please let me know if you are interested in trying to build it on some other platform.
When you type ltroot, it actually runs a script which sets the ROOTSYS environment variable and checks in $LIGOTOOLS/root for "Logon" scripts for all LIGOtools packages, which have names of the form <package>Logon.C. All such Logon scripts are passed to ROOT for execution at startup.
The ROOT macro search path is set, in $LIGOTOOLS/packages/root/<version>/root/system.rootrc, to include the $LIGOTOOLS/root directory. If you have your own .rootrc file which sets the macro search path, it will override this one in system.rootrc. So you should be sure that your search path includes "$(LIGOTOOLS)/root".

Documentation

Type ltroot -h for usage information.
You can suppress the loading of LIGOtools package extensions to ROOT by including the -s flag on the command line; in this case, ltroot behaves like an ordinary version of ROOT.
Complete documentation about ROOT, including a User Guide, is available from the ROOT home page, http://root.cern.ch.

Distribution files

Normally, you should use the ligotools_update utility to download and install new packages or new versions of existing packages, since it automatically figures out what packages need to be updated. However, if you wish to do so manually, then click on the name of the appropriate distribution file (below) with the right mouse button and choose "Save Link As..." from the popup menu. Note that you must save it on your disk with exactly the same name as it has on this web site. After the file has been downloaded, do:
ligotools_install <file>
where <file> is the file which was downloaded. This procedure will be quicker if the environment variable LIGOTOOLS is set to the main LIGOtools directory.

Binary distribution for Solaris: root_3.02.07a_SunOS.tar.gz (11,008 kb)
Binary distribution for Intel Linux: root_3.02.07a_Linux.tar.gz (10,653 kb)
Source distribution: root_3.02.07a_SOURCE.tar.gz (6,877 kb)
This is known to build properly on Solaris and Linux using gcc; other operating systems or compilers will require some modifications (e.g. to Makefile and ConfigArgs; also, you may need to download the appropriate ttf library).
