I have installed TOPAS, Tool for Particle Simulation Version 3.1.p3 .
When I run the examples of OriginCounts.txt in TOPAS this the error it is showing kindly suugest solution for this problem. Scoring and Qt problem.
Attempt to the run in Qt mode when TOPAS was build against a GEANT4 with no Qt.
Rebuild against a version of GEANT4 that has Qt or change Ts/UseQt to False."
Topas is exiting due to a serious error in scoring setup. Sc/MyScorer/Quantity has unknown value: OriginCount
