Dear support / users,
I’ve received an n-tuple, where I see the following structure.
The result is that the MakeFile of the TTree B has all the trees listed, and the few branches.
The problem I have, is that I don’t know how to access the trees and loop over them… Any ideas/suggestions?
Many thanks!
Stefanos
Hi,
what do you mean by
?
Could you share the file?

Hello!
Certainly! I’m also pasting here the dump of the tree showing the variables nested within each branch

Thanks a lot!

Hi Stefanos,
could you put me in condition of reproducing the issue with
o The input file
o The instruction to reproduce the attempt to read it
Cheers,
Danilo
Hi Danilo!
I’m terribly sorry for that… Actually, but calling the names of the variables from the header files in the script seems to work… What isn’t straightforward to do, is to plot a variable just by loading it and use command line, but I’ll settle with the first…
Thanks again!
Stefanos
