Dear Rooters, I've got two TTrees, tree1 and tree2, with the same variable list (EventNum X Y Z). I'd like to select those events in tree2 which have the same EventNum as the events in tree1. I can do this with a couple of for loops but it takes too long. I also tried this: Int_t numberOfEvents = tree1->GetEntries(); Char_t myString[20]; for (Int_t i=0; i<numberOfEvents; i++) { tree1->GetEvent(i); sprintf(myString,"\"EventNum == %d \"",EventNum); tree2->Draw(">>+eventList",myString); } but that didn't work. I tried a similar thing with a TCut object instead of myString...didn't work either. Any ideas? I'm using root version 3.10/02, gcc 3.2.2, RH9.0. Many thanks, Mike.
