[phenixbb] Real_space_refinement at low resolution question

Dear phenix users, I was wondering if it could be correct to exclude the real_space_refinement step working with a 3.3 A resolution map: I noted that in every real_space_refinemet step phenix told me that it was not useful. How can I exclude the routine from the command line? I am using 1.7.3-928 version. Fulvio Saccoccia, PhD student Dept. of Biochemical Sciences Sapienza University of Rome
