Dear Rooters,
I am trying to merge different numbers of root files using the "Tchain->Add" method. I am using the following script
-------------------------------------------------------------------------
TChain * chain = new TChain("EGAMMA");
for (Int_t ifil_os = 1; ifil_os < 20; ifil_os++) {
Char_t namefile_os[16];
strcpy (namefile_os, "egamma_60_875Events_");
Char_t numfile_os[4];
sprintf (numfile_os,"%d",ifil_os+1);
Char_t endfile_os[6];
strcpy (endfile_os, ".root");
// strncat (namefile, numfile, endfile);
TString mystring_os = "/home/jha/work/shaping/original_geometry/root
_file/60_GeV/";
chain->Add(mystring_os+namefile_os+numfile_os+endfile_os);
}
-----------------------------------------------------------------------
When I run the script, I faced with the following error
"Error in <TFile::TFile>: file /home/jha/work/shaping/original_geometry/root_file/60_GeV/egamma_60_875Events_2.root does not exist
Error in <TFile::TFile>: file /home/jha/work/shaping/original_geometry/root_file/60_GeV/egamma_60_875Events_2.root does not exist
Error in <TFile::TFile>: file /home/jha/work/shaping/original_geometry/root_file/60_GeV/egamma_60_875Events_2.root does not exist
..
..
"
and the program is still running with the above message.
However, the above file exists in the mentioned folder. I am able to browse the contents of the above root file using TBrowser. Please let me know where I am committing the mistakes.
Thanks for help.
With regards,
manoj jha
