Hi Jane, Currently, we have only one fitter (TFitter) based on Minuit. By default, TVirtualFitter::Fitter creates a TFitter object that uses TMinuit. You can also use TMinuit directly. minexam.cxx illustrates the use of a TVirtualFitter in general. The same code should run if we decide to add or switch to a different fitter in the future.
