GAMOS is a GEANT4-based framework that is at the same time easy-to-use and flexible.
The comprehensive scripting language makes it easy to implement the most common requirements of a Medical Physics application, without any need of C++ coding.
The plug-in technology, together with a careful modular design, a detailed documentation and a set of examples and tutorials that explain in detail how to extend the framework in different directions allows to exploit the full flexibility of GEANT4, by creating new user code or by reusing any piece of GEANT4 code and mixing it seamlessly with the existing GAMOS components.
Thanks to its big flexibility, already a sensible fraction of the over 1000 GAMOS users work in other fields than medical physics. If this is your case we recommend you to have a look at the 'Histogram and Scorer tutorial'
