Reading a given tree across multiple root files

Thank You @Danilo,

Yes this is quite helpful.
A quick follow up, the analysis requires the one branch values to be modified by a polynomial function

Value = p0 + p1*value + p2*(value)^2

However the p0, p1 and p2 are duffer for each file containing tree.

In this scenario is it possible to use TChain to merge the entries and still treat them with the different coefficients for file or

I need to loop through each file and use RVecOps as mentioned here

Please share if I haven’t been able to clarify myself. Thanks

Thanks a lot
