Yes, running dev-1420, using exactly the same .eff file except for serial number, the problem is gone. R-free actually improves in the "end" step, with almost no change on correcting solvent mask. Thanks! start: r_work=0.2315 r_free=0.2704 n_reflections: 87125 start: r_work=0.3154 r_free=0.3389 (reset all scales to undefined) bulk-solvent and scaling: r_work=0.2326 r_free=0.2699 remove outliers: r_work=0.2326 r_free=0.2699 correct solvent mask: r_work=0.2314 r_free=0.2700 final: r_work=0.2314 r_free=0.2700 n_reflections: 87125 Pavel Afonine wrote:
Hi Ed,
please try latest build - this keeps changing from build to build. If this doesn't fix it then please send me the files off list and I will investigate.

I'm refining a structure with phenix-dev-1414 version, and R-free decreases until the last step where R-work drops sharply and R-free increases. Am I doing something wrong?

Looking in the log file, it seems that this happens at the stage of correcting the solvent mask: ============================= updating all scales =============================
