Hi Dean,

just call gSystem->cd("src") before calling MakeClass:

 > #include "TChain.h"
 > int main (int argc, char* argv[])
 > {
 >   TChain chain("MyTree");
 >   chain.Add("filename.root");
     gSystem->cd("src");
 >   chain.MakeClass("Variables");
     gSystem->cd("..");

 > return 0;
 > }

Cheers, Axel.

Is there a way to tell root to use a different working directory (real directory, not in the ntuple)? I've tried using MakeClass("src/Variables") but this creates a class called "src/Variables", though it is in the correct directory it is not so desirable...
