Hi, The problem I have is that I build up a rather complicated set of cuts using TCut. Is there currently no way to see if a particular Tree or Ntuple entry satisfies a TCut? If not, that would mean I have to manually retype everything in the TCut and put it in if(...) statements. Scott > > Scott, > The TTree::Select function is currently dummy.
