This should not fail.
Could you please provide us with enough information (aka access to enough of your root files) to reproduce the problem?

Cheers,
Philippe.

Subject: [ROOT] Chain Merge Problem: details

Dear Rene,

sorry for the previous (not very precise) mail. I am running ROOT 5.13.02 on OS X 10.4. I have made a macro that I execute with the standard .x command. In a macro I am using the following list of commands

TChain *chain_ncal = new TChain("Eventi"); for(int s=0;s<=run_max;s++)
{   

sprintf(fn_root,"Run_%s/run%s.root",namerun[s],namerun[s]);

   printf("%s\n",fn_root);
   chain_ncal->Add(fn_root);
 }
chain_ncal->Print();

This works properly adding to the chain 7 files 4.4MB large. As soon as I add a line like

chain_ncal->Merge("all.root");

it gives me an error. The gdb output is attached at the end of the mail.
Why? How can I merge the chain into a single file. thx

Francesco
