[phenixbb] riding hydrogens

Hi, I used phenix.reduce to add riding hydrogens. After phenix.refine, the structure got a good score from MolProbity. However, if I stripped the riding hydrogens from the structure and let MolProbity to add hydrogens before the analysis, I got a much worse score, especially the clash score. Does phenix.refine refine the hydrogen positions? -- Jianghai
