Well, Dear Mighfar,<br>        What I am talking about is the new script, there are only one Cu atom in it, while the only one didn&#39;t show up under <a href="http://scf.in">scf.in</a> file. <br>        Thanks all the same.<br>

Dear Chengyu,<br>
your Cu atom is quite showing up in xcrysden! It<br>
is a Cu chain along the axis of your cnt.<br>

&gt; Dear Professor and everyone,<br>
&gt;      I  have successfully run the scf<br>
&gt; calculation for a (6,6) cnt, and get<br>
&gt; converged. Thanks for all your advice. Now my<br>
&gt; boss want me to add a copper<br>
&gt; atom in it, and do more calculations. I added<br>
&gt; one, but the copper atom<br>
&gt; cannot show in xcrysden, although again show in<br>
&gt; .xyz files. I don&#39;t know<br>
&gt; what the problem is , and I don&#39;t know if my<br>
&gt; script is right for a cnt+<br>
&gt; copper calculation, may anyone have a look at<br>
&gt; it?At least I need to find the<br>
&gt; copper atom out first.<br>
