But we are not able to solve the data set using CCP4 suite. The software is picking up only the lower resolution data but not the higher resolution data points. Also we are not able to merge data two sets, one with 2theta at 0deg and the other with 2theta at 20deg. Is there anyway to solve the data. Any help will be truly appreciated. Thank you in advance.
