[phenixbb] rfree set

Hi I converted mtz to xplor file and did the refinement . Also trying to use mtz file as it self, phenix complaining about MDchecksum Rfree. I do have F, SIGF, I, IMEAN , Rfree-flags in the mtz file, converted to xplor format, phenix did not give me any warning about MDchecksum, Any suggestion thanks ram
