[chimerax-users] Distance between two atoms

[Elaine Meng]

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
