Although each atom in a residue should have a different name, I guess your model #1.1 has more than one residue. If you hover the mouse over the atom you are interested in, the pop-up information should include both the residue number and the atom name, which you can include in the command to narrow it down, for example:<br>
<br>
sel #1.1:2@N z<5<br>
<br>
(atom named N in residue 2 of model 1.1). Or, if you don’t mind doing it interactively, you could Ctrl-click to select the atom you want and then use “sel” to specify it, for example:<br>
<br>
sel sel z<5<br>
<br>
Although you might think that wouldn’t work, it does!<br>
I hope this helps,<br>
