Detailed Description

Class used to obtain vector of all compatible TMs associated to a trajectory to be used by the NuclearTester.

The method run gets all compatible TMs of all TMs associated of a trajectory. Then it uses the NuclearTester class to decide whether the trajectory has interacted nuclearly or not. It finally returns a pair of the TM where the nuclear interaction occurs and all compatible TMs associated.
