[phenixbb] is there any phenix utility that can evaluate the Patterson Correlation function between exp and model data?

Hi, If I only have the experimental and model scattering factors (without model coordinates), is there any phenix utility that can evaluate the Patterson Correlation function between exp and model data? By the way, is the one by FFT as described in (http://www.nature.com/nature/journal/v473/n7348/full/nature09964.html) implemented in Phenix? Thanks a lot! Hailiang
