This is actually part of my project. My project is to build a MLP.
I’m a newbie to programming.
I have multiple files in seperate directories.
In each file there is a TTree with same name.
In the TTree, there is lots of variables.
I need a TTree(merged from multiple files)
with selected variable. (not all)
I want a loop to set all TTree in multiple file
and set the variable branches statues to 1,
then Get Entry and fill them into a new TTree (for input to MLP)
I did try with loops, but it turn out lot of errors
so I try to break some loops and type each line myself.
but it turn out error TTree fill
my code in Attachment.
So I need some help on this error,
n how can I modify it using loops, so i can set all setting
without everytime changing the code itself.
or maybe should I do it in a different method?
