[phenixbb] unknown parameters file format?

Hi all, I tried to create my own set of refinement parameters by copying sections of a .def file to a new file I called myrefine1.params. When I tried to use this for phenix.refine from the command line I received this error message: Sorry: Unknown file format: myrefine1.params What should I do? Thanks, Kyle Kyle T.
