David, In your phenix parameter, select "phs" as map_coeffcients_format, the phs file can be read directly by xfit. Below is my parameter's map section: electron_density_maps { map_format = *xplor map_coefficients_format = *mtz *phs suppress = None map { mtz_label_amplitudes = "2FOFCWT_new" mtz_label_phases = "PH2FOFCWT_new" likelihood_weighted = True obs_factor = 2 calc_factor = 1 } map { mtz_label_amplitudes = "FOFCWT_new" mtz_label_phases = "PHFOFCWT_new" likelihood_weighted = True obs_factor = 1 calc_factor = 1 } } Regards, Tongqing Tongqing Zhou, Ph.D. Staff Scientist Structural Biology Section Vaccine Research Center, NIAID/NIH Building 40, Room 4607B 40 Convent Drive, MSC3027 Bethesda, MD 20892 (301) 594-8710 (Tel) (301) 793-0794 (Cell) (301) 480-2658 (Fax) ****************************************************************** The information in this e-mail and any of its attachments is confidential and may contain sensitive information.

I still find xfit handy for a few things. D
