= What have we proposed?

 Fragment extension:: ChimeraX requests Phenix to propose placement of the next several residues in a cryoEM map.
 Ligand placement:: ChimeraX requests Phenix to place a flexible ligand in a user selected region of a cryoEM map.
 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.
 Validation:: ChimeraX will request validation problem lists from Phenix and allow user to fix problems, and request Phenix to run re-refinement.
 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.
