Re: std::vector<std::string>*

Hi,

MakeClass does not like object (including vectors), you need to remove the SetMakeClass(1). With newer version of ROOT (5.28 and up), you should be able to also disable the MakeClass mode just for the branch containing the your vector (i.e. call SetMakeClass(0) on the branch.

Cheers,
Philippe.
