Hi Zaldy, This behavior is not normal but I am not able to reproduce it. > 1. Is TChain sensetive to dates? No. > 2. How do we explain this behaviour? I don't really know. If I had to make a (wild) guess, I would say that it is possible that the file-system was not (yet?) fully synchronized when you tried to load the chain (i.e. for some reason the method use to look up the directory list by ROOT was not up to date (i.e. a file system or OS deficiency). > 3. How do we correct this without deleting and remaking directory? and, To investigate the problem further you want to simply the test by simply doing: root[0]Tchain cc("PedTree"); root[1]cc.add("../SelectedPedRootFiles/*.root"); root[2]cc.ls(); > firstlisting in the different case and look at the list. > 4 Is this a bug? Most likely. but we don't know from where. Cheers, Philippe. -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch]On Behalf Of zaldy Sent: Thursday, August 14, 2003 9:18 PM To: roottalk@pcroot.cern.ch Subject: [ROOT] TChain does not reflect new root files in Makeclass("...."); Dear Rooters, I found a strange behaviour of TChain. Let me describe it. I have about 2500 root files and place it at directory ../Data_analysis/SelectedPedRootFiles at directory ../Data_analysis/src i did root[0]Tchain cc("PedTree"); root[1]cc.add("../SelectedPedRootFiles/*.root"); root[2]PedTree->MakeClass("TRootPedSelected"); then an initial code is created. Now I have additional root (about 800 root files ) files and I wanted to add them on same directory "../Data_analysis/SelectedPedRootFiles". The new root files are exacly same tree name structure. And I place the (new root files) in the same directory ../Data_analysis/SelectedPedRootFiles In this case I have to regenerate a new TRootPedSelected.C and TRootPedSelected.h files via PedTree->MakeClass("TRootPedSelected); to reflect the new rootfiles. So at "../Data_analysis/src" I remove the file name "TRootPedSelected.*" so as not to be in conflict with the new one. at directory ../Data_analysis/src I repeated the procedure as before. root[0]Tchain cc("PedTree"); root[1]cc.add("../SelectedPedRootFiles/*.root"); root[2]PedTree->MakeClass("TRootPedSelected"); The strange this is this: the new root files are not included in the chain. -------------------> Now, I move all the root files this time to a new currently created directory ../Data_analysis/investigate Then at ../Data_analysis/src I did repeated the procedure again. .... root[1]cc.Add("../investigate/*.root"); ..... Result is: the new root files are reflected. ------------------> Now I want to use the old dir name: SelectedPedRootFiles (my preference) So at dir ../Data_analysis , i did; $rm -r SelectedPedRootFiles $mkdir SelectedPedRootFiles then mv all my rootfiles(including the new) from ../Data_analysis/investigate to ../Data_analysis/SelectedPedRootFiles NOTE: Situation now is same as before, only that I deleted the dir SelectedPedRootFiles, then recreate again. Now at dir ../Data_analysis/src I did root[0]Tchain cc("PedTree"); root[1]cc.add("../SelectedPedRootFiles/*.root"); root[2]PedTree->MakeClass("TRootPedSelected); then a initial code is created. Result: The new root files and the old ones are reflected. ------------------> Questions: 1. Is TChain sensetive to dates? 2. How do we explain this behaviour? 3. How do we correct this without deleting and remaking directory? and, 4 Is this a bug?
