I just remember that "malloc" is one of the things not to be used in c++ ... My current idea is to read in an stl container and than copy this to an array. The obvious way would be to use knowledge about how vector is implemented in stl, but this I do not like. I was looking for something like vector::MakeArray(), which doesnt seem to exist. Pity ... Anyway, thanks for the confirmation of the missing stl ... BTW, the latest version 3.02 offers a TGraph::TGraph(TVector, ....), which could help a bit. But unfortunately I need a TGrahpErrors, which seems not yet to be updated ... Michael
