Hello, we added some data members in a class, but now we are not able to read the old root trees. The only hint I found in the digests is to add some lines in the streamer function like: if (R__v > 1) { R__b >> newdata;} But I think the streamer function is created automatically, so I have to add it after the creation of EventDict.cpp, each? Or is it possible to do this version management also automatically? Thanks for your help, Ingo -- Ingo Froehlich, II.
