Well I am having fish tonight 😉. I used your suggestion select the atoms on the screen and then run the pop-up distance command and reading the results in the Log. I am still not fully clear about defining atoms and such after reading the atoms page. I
will keep working on it.</div>

<div class="PlainText">Hi Phil,<br>
There is a "distance" command, use command "help distance" or see the help at our website here:<br>
<<a href="https://rbvi.ucsf.edu/chimerax/docs/user/commands/distance.html">https://rbvi.ucsf.edu/chimerax/docs/user/commands/distance.html</a>><br>
<br>
...and many examples of how to specify atoms in the command line here:<br>
<<a href="https://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html#hierarchy">https://rbvi.ucsf.edu/chimerax/docs/user/commands/atomspec.html#hierarchy</a>><br>
<br>
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.<br>
<br>
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):<br>
