Detector Definition and Response• Size of the scoring mesh. Mesh size must be specified as "half width" similar to the arguments of G4Box.• Number of bins for each axes. Note that too hugh number causes immense memory consumption.• Optionally, position and rotation of the mesh. If not specified, the mesh is positioned at the center of the worldvolume without rotation.For a scoring mesh the user can have arbitrary number of quantities to be scored for each cell of the mesh. For eachscoring quantity, the use can set one filter. Please note that /score/filter affects on the preceding scorer.Names of scorers and filters must be unique for the mesh. It is possible to define more than one scorer of samekind with different names and, likely, with different filters.Defining a scoring mesh and scores in the mesh should terminate with the /score/close command. The followingsample UI commands define a scoring mesh named boxMesh_1, size of which is 2 m * 2 m * 2 m, andsliced into 30 cells along each axes. For each cell energy deposition, number of steps of gamma, number of stepsof electron and number of steps of positron are scored.Example 4.22. UI commands to define a scoring mesh and scorers## define scoring mesh#/score/create/boxMesh boxMesh_1/score/mesh/boxSize 100. 100. 100. cm/score/mesh/nBin 30 30 30## define scorers and filters#/score/quantity/energyDeposit eDep/score/quantity/nOfStep nOfStepGamma/score/filter/particle gammaFilter gamma/score/quantity/nOfStep nOfStepEMinus/score/filter/particle eMinusFilter e-/score/quantity/nOfStep nOfStepEPlus/score/filter/particle ePlusFilter e+#/score/close#4.8.3. Drawing scoresOnce scores are filled, it is possible to visualize the scores. The score is drawn on top of the mass geometry withthe current visualization settings.Figure 4.10. Drawing scores in slices (left) and projection (right)By default, entries are linearly mapped to colors (gray - blue - green - red). This color mapping is implementedin G4DefaultLinearColorMap class, and registered to G4ScoringManager with the color map name141
Detector Definition and Response"defaultLinearColorMap". The user may alternate color map by implementing a customised color mapclass derived from G4VScoreColorMap and register it to G4ScoringManager. Then, for each draw command,one can specify the preferred color map.4.8.4. Writing scores to a fileIt is possible to dump a score in a mesh (/score/dumpQuantityToFile command) or all scores in a mesh(/score/dumpAllQuantitiesToFile command) to a file. The default file format is the simple CSV. Toalternate the file format, one should overwrite G4VScoreWriter class and register it to G4ScoringManager.Please refer to /examples/extended/runAndEvent/RE03 for details.142
