Hello, I'm working in a refinement that I started some time ago. I noted that repeating the same refinement task using a newer version of phenix, the refinement statistics Before and After refinement are different from values of the old version (I used "restore job" from the Job history to repeat the same task in the two versions installed in the same PC). Any explanation? I'm worried about the rms deviation. Thanks in advance.

new version:

R-work: start=0.1697, final=0.1761

R-free: start=0.2011, final=0.2053

Bonds: start=0.046, final=0.029

Angles: start=1.321, final= 0.631

old version:

R-work: start=0.1651, final=0.1657

R-free: start=0.2018, final=0.2009

Bonds: start=0.013, final=0.013

Angles: start=1.409, final= 1.411
