Hi Matt,
There is some information about how to install Python packages with Chimera in the programming FAQ
https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/faq.html#q3b
but I believe Eric here said the suggested approach to doing pip install no longer works. A more hacky approach is to simply copy site-packages/Mido (or whatever the module is called) from your system installed version into the Chimera Python site-packages (in chimera/lib/python2.7/site-packages or Chimera.app/Contents/Resources/lib/python2.7/site-packages on Mac).

I don’t know of an adequate Qt / MIDI library exists. Really we would want PyQt5 / MIDI since all Qt in ChimeraX is done in Python. The top Qt / MIDI hit is the QMidi library

Hi,
Is it possible to find the axis of symmetry for a dimer? I am looking to
rotate the dimer along this axis by 180 degrees so that I can compare the
two structures.
Thank you.

Kavya Shankar
