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 *

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?
Thanks for any advice or help,
alessio
