-Atomic model buiding 1
Software | Name: UCSF Chimera |
---|---|
Details | The model was refined by iterating between manual edits in Coot, molecular dynamics-guided edits using the ISOLDE ChimeraX package, and automated real-space refinement in Phenix. Models that had been automatically rebuilt using Rosetta were used as guides during manual refinement. |
