Hi all, I'm trying to merge some ntuples with Version 3.05/07 and I'm having problems with the produced ntuple. The merging of the trees shows no problem: the macro runs fine and I can open the "merged" file. I can even call the Draw() function on the merged TTree. But when I try to use the Scan() function or the Show or the Loop one I have problems. The merged ntuple contains TVectors (below I show the content of my ntuple...) //Declaration of leaves types Int_t evt; Int_t nadc; Int_t ntdc; Int_t ntdc128; Int_t adcM[8][1]; Int_t tdcM[8][1]; TVector *Shit; TVector *Sch; //List of branches TBranch *b_evt; //! TBranch *b_nadc; //! TBranch *b_ntdc; //! TBranch *b_ntdc128; //! TBranch *b_adcM; //! TBranch *b_tdcM; //! TBranch *b_Shit; //! TBranch *b_Sch; //! Here's my problem.. root [1] ((TTree*)gDirectory->Get("data"))->Scan(); ************************************************************************************************************ * Row * evt * nadc * ntdc * ntdc128 * adcM * tdcM * Shit * Sch * ************************************************************************************************************ *** Break *** segmentation violation Generating stack trace... /usr/bin/c++filt: unknown demangling style `gnu-new-abi' Root > I've used the merging routine to merge other root files and everything works fine: am I doing something wrong or there's a problem merging TVectors?
