Item Description

The real-space (linear) correlation coefficient RSCC, as described by Jones et al. (1991), evaluated over all atoms in the nucleic acid monomer. sum|pobs - <pobs>| * sum|pcalc - <pcalc>| RSCC = ------------------------------------------------- [ sum|pobs - <pobs> |2 * sum|pcalc - <pcalc>|2 ]1/2 pobs = the density in an 'experimental' map pcalc = the density in a 'calculated' map sum is taken over the specified grid points Details of how these maps were calculated should be given in _struct_mon_details.RSCC. < > indicates an average and the sums are taken over all map grid points near the relevant atoms. The radius for including grid points in the calculation should also be given in _struct_mon_details.RSCC. Ref: Jones, T. A., Zou, J.-Y., Cowan, S. W. & Kjeldgaard, M. (1991). Acta Cryst.
