= Discussion =

* Chimera web services
  - Eric made Chimera MUSCLE service use ChimeraX REST.
  - Did not work on session restore of ongoing jobs.
  - Do we need to distinguish Chimera vs ChimeraX web requests.  Can add user agent to queries.
  - Not essential that we distinguish requests.
  - Zach will work to allow user agent to be specified in web services client code.

* ChimeraX library use case
  - Decided to allow opening a PDB/mmCIF file and compute hydrogen bonds between two sets of atoms (e.g. ligand and protein).
  - Won't allow image saving in first library release.
  - Will need to decide whether to distribute on PyPi or Conda or both.
  - Fervent discussion on whether to try to exclude the UI code from the wheel.
  - Zach will discuss progress at group meeting on January 18.
  - Library deadline is April 2023.
