+### Int_t MCtruth()
+Reads a tree, performs the truthmatching based on the settings in [[GlobalFunctions.hpp|GlobalFunctions.hpp]], creates, fills and saves a lot of mass and TRUEID histograms. Saves the truthmatching branch in a new tuple. The old tuple is backed up and overwritten by the new tuple. The meaning of the parameters is in [[BDTSelection.cpp|BDTSelection]].
