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

It is just the standard linear correlation coefficient (using i_obs
and i_model for x and y), which is very easy to calculate. In another
email you wrote that you want to do refinement. What are your
variables?
