Re: Writing fitting parameters into a seperate file

Alternately, if you don't want to write any additional lines of code just cast the standard output to a file by executing root as: root -l myfile.C > output.log
note that you won't be notified about any errors occurring and EVERY output is casted.
If you use MINUIT, the parameters together with their uncertainties can be extracted by:
TVirtualFitter::SetDefaultFitter("Minuit"); gMinuit->GetParameter(Parameter,Value,Uncertainty);

Cheers,
Stephan
