Hi Tom, Thanks a lot for your reply! I actually need to use both... I use 'distance' to measure the distance between two points representing centers of mass. And I use 'measure distance' to measure the distance between an atom and a molecule. (I also use 'measure center ... mark true' to get the points of centers of mass, but I do not necessarily need the result in Python). Thanks for the Python command for 'distance'! Could you also point me to the command for 'measure distance'? Is there a way to find Python alternatives for an arbitrary Chimera commands? Thanks!

Sure here is the distance between two atoms.
import Midas d = Midas.distance('#1:395.A@CA #0:29.F@CA’)
I don’t know what you are doing since “distance #1 #2” won’t work unless each of those models is only one atom. And of course “measure distance” is a different command and has a different Python call to access it. Please be specific about what you need. I don’t want to guess all the different possibilities of what you are trying to measure the distance between.

Hi,
I'm measuring distance between two points. The measurement goes well and I get a correct value in the viewport. I would like to get the same value into a Python variable. Is it possible?
I'm thinking about a code like this:
d = chimera.runCommand('distance #1 #2')
However, it seems to be impossible to get any value from runCommand, I always get None...
Even parsing the log that appears in IDLE from commands 'distance #1 #2' or 'measure distance #1 #2' would sort-of work, but I don't know how to capture the log either...
Is there a way to get values into variables from 'measure distance'?
Thank you!
