Dear SasView team, I have some corrected SANS data that I am fitting with SasView. The system is SDS 10% in 90% D2O/20% H2O v/v (file 093220_230). I was able to fit it with "EllipsoidModel”, “HayterMSAStructure” (file M2[093220_230_out.txt). Could you please explain me how to extract the structure and form factor? What I tried was to: 1. Fit the data with the above mentioned model 2. Remove the structure factor (just by deselecting it in SasView) to obtain ONLY the form factor (no more fit was performed, only the calculation) 3. Save the curve that is supposed to be a form factor 4. Divide the original data by the form factor to get the structure factor If I do the other way round, so I fit the data, remove the form, fix the structure factor (RED) and from it I get the form (PURPLE CIRCLES) by dividing the original data (BLUE) by the structure, I get this curve: [cid:image001.png@...624...] The problem is that I do not see any realistic form factor, as the structure is not completely removed at low q. Do you have any suggestions, please? Thanks, Marco
