Hallo Rene, thanks for the fast fix. However, I have one more question ... The original problem occurs when using the Pluto++ package available from GSI. The class PParticle is actually derived from TLorentzVector. The following problem I observed so far only with PParticle. I had no time to check it with a separate test class. In the current Root version it should be possible to call member functions within TTree::Draw(). For the PParticle class all the member functions from the base class, i.e. PParticle::Theta() (-> TLorentzVector::Theta()) are working, but none of the additional functions of the derived class. Is this a restriction of Root or what must be done to enable it? Best regards, Volker -- Dr. Volker Hejny Tel: 02461/616853 ** Institut f.
