Dear Wahyu, You may do quantitative analysis without background refinement or subtraction using DDM: www.icct.ru/Eng/Content/Persons/Sol_LA/ddm.html

I want to do quantitative analysis using GSAS, however my diffraction pattern has very high and rough background which makes me difficult to do preliminary qualitative works to determine the available phases. Is it alright if I substract the background and refine it a little first using another refinement software before I go through GSAS? I really appreciate your kindness to answer. regards, wahyu
