Dear All, I have done the SF-Tool check for my protein crystal structure, and the result is as following. My 3 questions are (1) What does the following mean and how to solve the problem "Error! No labels are written for MTZ to mmCIF conversion Structure factor conversion is done?"  (2)Where there is no "Calculated phenix R_factor(all data)"? (3) Where there is no "Correlation (Fo-Fc)"? I am looking forward to getting your reply. Dialing Error! No labels are written for MTZ to mmCIF conversion Structure factor conversion is done. Header of the mtz file can be seen from here Click here to see the converted mmCIF file Checking Xray Data by PHENIX (model_vs_data) ... PHENIX (model_vs_data) is done.
