This course encompasses training material developed by several Geant4 members: thanks to all of them!

Analysis

In a Geant4-based simulation application

Strategy

Geant4 is a particle transport systemData analysis is out of its scopeA user is responsible for his/her own functionality for data analysis in his/her simulation application- Many software tools exist, which may be used for analysis of simulation

results

Basic strategy- Store simulation output in an appropriate format for further analysis- Process the data after the simulation is over using analysis tools

Several systems for data analysis are available- AIDA-compliant tools, ROOT, ...- Gnuplot, Matlab, Octave, ...- R

Choose an analysis tool according to your needs

Demo application in this course: AIDA + iAIDA + R

See N45-8 talk

Java Analysis Studio

iAIDA

AIDA

Interface to AIDA

No dependenceMinimize coupling of components

Through abstract interfaces

Interfacing to Geant4

Requires setting the environmental variable G4ANALYSIS_USE

AIDA (Abstract Interfaces for Data Analysis) can be used in Geant4 – Requires AIDA headers installed in the system– Requires an AIDA compliant tool for analysis

Tools for analysis compliant with AIDA interfaces currently are:– iAIDA (C++)– JAS (Java Analysis Studio)– Open Scientist Lab (C++)– PAIDA (Pyhton)
