Access a vector string

Hi All

An ntuple(D3pd) has trigger information stored as vector string. I am not able to access it similar to how i access vector float or int(example: jetpt,eta).

One of branch is trigger which is a vector string. And it has histogram having various triggers fired as bins. How can i access these trigger information?



It is not clear from your description what you tried and how it fails. Could you provide a concrete example (I am not sure even what you file organization is)? vector should work as well as vector in the general sense (in newer version of ROOT).
