Hi I'm trying to Merge about 100 root files (with 2 ntuples) into fewer files. I'm following the Brun's advice: root> TChain chain("h1") root> chain.Add("fil*.root") root> chain.Merge("outfile.root") But most of the time, when I give the 2nd command, root answer nothing, that means, it doesn't read the files, so I repeat the command and SOME TIMES it succeed to read them. To give the command chain.ADD again, I MUST get out of root, since giving this command twice, it get a segmentation violation. Loot the output below. root [0] TChain chain("h1") root [1] chain.Add("wphact20cc_e206.7_c1*.root"); root [2] chain.Add("wphact20cc_e206.7_c1*.root") (Int_t)0 root [3] chain.Add("wphact20cc_e206.7_c1*.root") *** Break *** segmentation violation Root > .q In fact, I had to kill the process since even the ".q" did not work. What is going on? What am I doing wrong? I'm using the "official" version at CERN (Version 3.01/06 12 July 2001). Thanks Luiz
