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.
Error :
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
Thank You
