This issues has been somewhat discussed several weeks ago. I need to use a large number of params in Minuit (~80 or so) and, as Rene explained in previous postings, I use the following constructor: TMinuit *aMinuit = new TMinuit(95); SEEK & SIMPLEX calls work ok, however all the Minuit functions that estimate parameter errors (such as MIGRAD, MINOS) dont work correctly for parameters 26 and higher (i.e. parabollic errors & correlations are correctly calculated for the first 25 parameters, but not for the rest of it -- somehow Minuit fixes err(p)=sqrt(2) for P>25). Is this a bug or I'm doing sth wrong? -mikula ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
