| 3 | Fragment extension:: ChimeraX requests Phenix to propose placement of the next several residues in a cryoEM map. |
| 4 | Ligand placement:: ChimeraX requests Phenix to place a flexible ligand in a user selected region of a cryoEM map. |
| 5 | Restraints:: ChimeraX will translate ISOLDE refinement restraints into Phenix format and hand off to Phenix. ChimeraX will display Phenix automatically generated restraints. An example restraint would be that a group of atoms is specified as rigid, or a metal position is held to nearby atoms. |
| 6 | Validation:: ChimeraX will request validation problem lists from Phenix and allow user to fix problems, and request Phenix to run re-refinement. |
| 7 | REST communication:: ChimeraX will utilize Phenix tools by making REST calls. Also Phenix will be able to send data to a ChimeraX REST server for visualization. |
