Welcome to Go4!          

 

New version: v4.7.0 with Qt3/Qt4
on Linux, Windows XP/7, and MacOS X support  (October
17th 2014)

 At GSI: . go4login 407-00

The object-oriented system Go4 (GSI Object Oriented On-line Off-line system)  is based on ROOT (R. Brun et al.) with the specific requirements of the low and medium energy nuclear and atomic physics experiments implemented as extensions.

Go4 separates analysis and GUI in two tasks which could run on different nodes. Communication is done through threads and sockets. The GUI is built with the Qt widget library using the Qt designer. Qt and ROOT are interfaced by QtROOT. Full ROOT functionality including menus and graphics is available without modifications. 
The Go4 analysis framework provides the syntax to organize the analysis in steps which can be controlled from the GUI. Each step has its own IO and processing classes. 
The Go4 event classes can be used to construct at runtime complex (composite) events which are stored by Go4 in trees and branches without explicit programming. 
The Go4 GUI includes a browser and tree viewer which can be used without analysis to process standard ROOT files. The tree viewer resolves arbitrary hierarchy levels of composite event trees. 

Status:

Go4 has been developed on Linux  and was tested e.g. in the following environments:
Suse 10.2 (x86_64), SuSe 11.3 (x86_64), SuSe 12.2 (x86_64), Debian 3.1, Debian 4.0 (32 bit and 64bit), Debian 5.0/6.0/7.x,  Ubuntu 11.10
with compilers: gcc 3.3.5, gcc 4.1.x, gcc 4.3.2, gcc 4.5.0, gcc 4.6.1
It should be portable to other UNIX platforms supported by ROOT.
Since May 08:  Go4 runs on Solaris (SunOS 5.2, CC 5.8)
New since November 09:  Go4 with full GUI on Windows XP/ Windows 7
New since May 2010: Go4 on Mac OS X 10.6 with Qt4-X11 (experimental!)
New since November 2013
:  Go4  with web-server as monitoring and control interface (requires DABC framework)
