In July 2016, I finished a refinement with Phenix dev-2376 with these final stats start final --------------------------------------- R-work: 0.1982 0.2007 R-free: 0.2376 0.2367 RMS(angles): 0.55 0.45 RMS(bonds): 0.003 0.002 Today, I reran the exact same parameter file and input files with Phenix dev-2712: start final --------------------------------------- R-work: 0.2073 0.2037 R-free: 0.2445 0.2442 RMS(angles): 0.55 0.45 RMS(bonds): 0.003 0.002 R-free values are now higher than they used to be. This fact was also flagged when I ran Table 1 today. -Mark _______________________________________________ Mark A.
