Hi Rooters. What is wrong? When I try to save TCutG object in the file I get a messages ERROR, Streamer is null TString* fNames offset=1448 type=501 [fNpar] Array of parameter names ERROR, Streamer is null TString* fNames offset=1448 type=501 [fNpar] Array of parameter names ERROR, Streamer is null TString* fNames offset=1448 type=501 [fNpar] Array of parameter names Object is saved. I can see and copy it in another file. But 1. When I quit from the root it returns with error 2. When file is opened in the next time I get a warning Warning in <TClass::TClass>: no dictionary for class TTreeFormula is available TCutG is written by the next commands char cutname[10]; TCutG *gcut; sprintf(cutname,"CUT%2.2iD%1iS5",nf,ndet); gcut = (TCutG*)gROOT->FindObject(cutname); gcut->Print(); //== This line work gcut->Write(); ROOT 3.02/04 for Windows.
