Hi Chiara,

The last line is not what you want (looking at the syntax, you access element no 3 of an array of TF1, i.e. a TF1, not a TF1*). This might work (depending on what GetFitFunctions() returns):

> root [2] TF1** f = ciccio->GetFitFunctions();
> root [3] f[2]->GetName()

As this is awkward and error-prone, you should always pass TLists* around, which contain the elements you currently store in a plain C array of TF1*. I.e. not TF1* f[3], but TList* listFunc; listFunc->Add(new TF1...).
