Hi Alicia,

a streamer is the method of the dictonary of a ROOT class which takes care about persiting an object to file (as far as I understand). When writing the class interface you can actually mark member variables which shall not be written (e.g. temporary objects created when the class is created) with a comment like

int member; //!

I noticed that the member variable fFile (see https://subversion.gsi.de/trac/fairroot/browser/pandaroot/trunk/hyp/PndH yp.h#L226) and perhaps others might be automatically streamed since they are not marked to be ignored by the streamer.

In summary, you could try to put a "//!" like

226	  TFile *fFile; //!
227	  TTree *ft; //!
228	  TClonesArray *fEvt; //!

and try whether this helps (just an idea, I'm not at all sure Wink

).

Best,
Klaus
