Header files for Trees

Dear All,

I need some general guidance, this may turn out to be more of a C++ question, but since i am using ROOT i thought this would be the best place to start. I have a large analysis that i am trying to make more modular. My issue now is that i have probalby about 100 branches in a TTree that i have to
declare at the top of my root macro. so basically i have

void analysis()
tree->Branch("name1", "title1")
tree->Branch("name2", "title2")
tree->Branch("name100", "title100")

i would love to have these hundred or so lines removed from my code and put into a header file.
i tried this by simply moving these definitions into a file “tree.h” with the proper header file syntax, and got a message:

I read somewhere that this error is because this syntax requires processing and the header file
does not do this. So, if not a header file then how would you best modularize a code so you dont
have 100’s of lines of branch declarations?

Any suggestions for how to achieve this?

Many Thanks,
