plot of 'absorbtion units' versus 'reverse nanometers'. And it looks absolutely different from structure factor from article I cited. For example in article SF is fading sinusoid while g_rdf gives me positive increasing curve. I suppose it's diffraction spectrum, not structure

I'm trying to repeat some X-ray diffraction analysis on lipid bilayers according to the article: http://dx.doi.org/10.1529/biophysj.104.046821 (it's free) I have several corrected OPLS all-atom bilayer models and I need to validate my model according to experimental x-ray diffraction data. But I
