Problems that need to be overcome by (XFIT, Crysfire, Refcel, UNITCELL); Chekcell and Rietica
Overlapping multi-phase powder patterns
Large amounts of raw diffraction data! (collecting 3 patterns each 5 to 300 seconds)
Intensities are near meaningless
- no incident intensity spectrum
- particle statistics problems
- preferred orientation problems
- X-ray absorption
