WebRe-refinement with a slightly different protocol is often helpful; in particular, explicit hydrogens can help constrain the model. The weight applied to X-ray terms during refinement may need to be reduced in favor of geometric restraints; this can be done automatically by phenix.refine. References WebIn both cases, you need to fit the small molecule into the electron density to complete the atomic model. As part of this process, you frequently need to generate appropriate …
