Is have 2 difference anomalous datasets with two different heavy atoms. I can input 2 SAD datasets in AutoSol using the Wavelength and Group = keywords. How do I input 2 different crystal_info keywords since this keyword does not accept the Group= option? cheers Nora Dr N B Cronin X-Ray Laboratory Manager Tel.
