Hi,
just a question: which momentum resolution are you giving at the beginning (I am not speaking about the smearing, just the momentum error).
Because I had a similar problem, and then I have found that I was setting the error to zero -> there was no fitting at all. Then I have started to put a 10% as initial momentum error, and the fitter started to fit Smile
