[chimerax-users] Possible to measure the shortest distance between two models?

[Tom Goddard]

You can use Python in ChimeraX to find the shortest distance.  Here is some example code closest.py to do that.

	https://rbvi.github.io/chimerax-recipes/closest/closest.html <https://rbvi.github.io/chimerax-recipes/closest/closest.html>

If you open that Python code in ChimeraX it registers a command "closest"

	open 7LUP
	closest /A to /B maxDist 100

	> Minimum distance 2.27 between /A LYS 45 NZ and /B ASP 522 OD1
