Small angle x-ray scattering (SAXS) has been a key technique in the structure determination of colloidal crystals especially in solution. When the structure becomes complex, it is essential to accurately calculate its x-ray scattering pattern. In this presentation, recent advances of SAXS data analysis on colloidal crystals will be discussed. A focus will be more on particle position determination in the unit cell. Two approaches, model analysis and Fourier synthesis, will be reviewed along with examples on DNA-NP assemblies. Complimentary use of these two methods will significantly improve data analysis and reduce effort.<br/>
