[ccp4bb] how to fix c-beta deviations

2012-02-15 Thread Anuradha Balasubramanian
Dear all, i am quite new to refinement and after refinement using refmac i have a resonable R-factor and R-free (22 and 27%), but Molprobity analysis shows c-beta devaition s as 23. How can i fix this? -- B. Anuradha Research scholar, CAS in crystallography and Biophysics, University of Madras.
