[Ifeffit] Novice FEFF user question

I am new to FEFF and I have a small problem. I'm trying to produce a XANES spectra of Cu (from the examples). I cannot seem to obtain the pre-edge region in my result. I have attached a screen shot. Could you tell me how to calculate the area before E0, i.e. from -50 to 50 eV. Thanks Sincerely -- M Menard, Ph.D.
