Hi all, I am refining a 2.75 A structure. The wxc_scale is 0.02, optimize_wxc is false. But the geometry I got doesn't make sense at all. Any explanations? ------------------------------------------------------------------------ stage angl bond chir dihe plan repu geom_target 0 : 0.617 0.004 0.039 14.275 0.003 4.123 5.8886e-02 1_bss: 0.617 0.004 0.039 14.275 0.003 4.123 5.8886e-02 1_xyz: 3.391 0.059 0.209 16.068 0.010 4.114 1.3055e+00 1_adp: 3.391 0.059 0.209 16.068 0.010 4.114 1.3055e+00 2_bss: 3.391 0.059 0.209 16.068 0.010 4.114 1.3055e+00 2_xyz: 2.435 0.032 0.180 15.961 0.007 4.114 5.4206e-01 2_adp: 2.435 0.032 0.180 15.961 0.007 4.114 5.4206e-01 3_bss: 2.435 0.032 0.180 15.961 0.007 4.114 5.4206e-01 3_xyz: 2.139 0.025 0.191 15.477 0.007 4.114 3.7907e-01 3_adp: 2.139 0.025 0.191 15.477 0.007 4.114 3.7907e-01 ------------------------------------------------------------------------ Thanks. -- Jianghai
