Dear root users,
I tried to creat a TChain to chain 2 trees in 2 root files as
follows:
root{] TChain chain("tt")
root[] chain.Add("file1.root")
root[] chain.Add("file2.root")
root[] tt.StartViewer()
After typing the first 3 lines, nothing wrong happens. That seems the
TChain is created. But after typing the 4th command to view the content
of the TChain, an error appears:
Symbol tt is not defined in current scope FILE:(tmpfile) LINE:1
Failed to evaluate tt.StartViewer.......
I've checked the tree name of both trees separately before with the Tree
Viewer. So I'm very sure the name is "tt". So is there anything I can do
to solve this problem?
Thank you very much!
Lesley
