I am having a question about map calcultation.

It seems that phenix.maps can do the job, but I did not find a good
document on how to run it. In its help information, a parameter file is
I tried do use parameter file for refinement, which has been

phenix.maps --unused_ok yyy.mtz xxx.pdb refine.param
but phenix.maps report the error
