Hello Lei, I don't have answer but if you send me data and model files then I will have a look and may be I notice something worth taking care of. Pavel On 1/17/14, 2:14 PM, rainfieldcn wrote:

Hi All, I am doing refinement on some low resolution structures ( around 4A ). I used wxc_scale=0.15 before on phenix.refine: 1.8.2_1309 I got: REMARK 3 DEVIATIONS FROM IDEAL VALUES. REMARK 3 RMSD MAX COUNT REMARK 3 BOND : 0.006 0.048 24993 REMARK 3 ANGLE : 1.049 11.841 33849 REMARK 3 CHIRALITY : 0.044 0.323 3843 REMARK 3 PLANARITY : 0.005 0.053 4276 REMARK 3 DIHEDRAL : 14.080 87.581 8889 REMARK 3 MIN NONBONDED DISTANCE : 2.098 REMARK 3 MOLPROBITY STATISTICS. REMARK 3 ALL-ATOM CLASHSCORE : 10.49 REMARK 3 RAMACHANDRAN PLOT: REMARK 3 OUTLIERS : 0.10 % REMARK 3 ALLOWED : 3.84 % REMARK 3 FAVORED : 96.06 % REMARK 3 ROTAMER OUTLIERS : 3.87 % REMARK 3 CBETA DEVIATIONS : 0 now, phenix is updated to phenix.refine: 1.8.4_1496. and I got: REMARK 3 DEVIATIONS FROM IDEAL VALUES. REMARK 3 RMSD MAX COUNT REMARK 3 BOND : 0.016 0.237 24993 REMARK 3 ANGLE : 2.262 36.773 33853 REMARK 3 CHIRALITY : 0.099 2.724 3847 REMARK 3 PLANARITY : 0.010 0.102 4280 REMARK 3 DIHEDRAL : 14.585 89.962 8889 REMARK 3 MIN NONBONDED DISTANCE : 1.923 REMARK 3 MOLPROBITY STATISTICS. REMARK 3 ALL-ATOM CLASHSCORE : 17.57 REMARK 3 RAMACHANDRAN PLOT: REMARK 3 OUTLIERS : 0.32 % REMARK 3 ALLOWED : 4.07 % REMARK 3 FAVORED : 95.61 % REMARK 3 ROTAMER OUTLIERS : 4.22 % REMARK 3 CBETA DEVIATIONS : 39 So I am wondering if there is some bug in phenix.refine that wxc_scale doesn't work? Thanks, Lei
