[chimerax-users] [Ext] Re: Display chain annotations w/o having to reopen files

[Eric Pettersen]

No, as long as you're using --nogui (which it certainly sounds like you should be here) the Log tool will not be started and therefore will have no saved state to restore when the session gets restored.  As a hack until that enhancement ticket gets implemented you can force the chain table into the log (after the session is restored) with this code:

	from chimerax.atomic import Structure
	for m in session.models:
		if isinstance(m, Structure):
			m._report_chain_descriptions(session)

You could put that in a .py file and use 'open' to run it.  As an additional hack, you can pretend it's a "preset" and add it to the Presets menu (see Presets→Add A Preset...) so you can easily execute it using that menu.
