Hi Phil, There is a "distance" command, use command "help distance" or see the help at our website here: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/distance.html> ...and many examples of how to specify atoms in the command line here: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html#hierarchy> Why don't you give it a few tries? We need to "teach a man to fish" since we can't tell thousands of users how to write each command they need for their research. Or you can just choose the atoms from the screen: first make sure they are displayed so you can actually see them, and then Ctrl-click one, Shift-Ctrl-doubleclick the second one and choose "Distance" from the resulting pop-up menu. This also is described in the help (Selection Context Menus): <https://rbvi.ucsf.edu/chimerax/docs/user/selection.html#context> Best, Elaine ----- Elaine C.

Hi Everyone,
I have a two chain model. I would like to determine the distance between the CD1 atom of residue 77 in chain B and the CD1 atom of residue Leu 150 in chain C. What would be the proper distance command.
Thanks for the help again.
