ROOT NTuple Analysis using MakeClass
For NTuple analysis ROOT provides a
MakeClass command that produces analysis skeleton.
Assuming you have an analysis file
myfile.root
containing one tree
CollectionTree
NTuple analysis skeleton is created like this:
>root myfile.root
>CollectionTree->MakeClass("an_skeleton_name") //produces .h and .C files
Analysis can be implemented in the
an_skeleton_name::Loop
method which loops over all entries.
For efficiency comment out the branches and variables in the
an_skeleton_name.h
and
an_skeleton_name.C
files you're not using.
