<p class="MsoNormal">Hi, all<u></u><u></u></p>
<div>
<p class="MsoNormal">  i am new to cp2k, please  forgive me for my questions may be a trival.<u></u><u></u></p>
<div>
<p class="MsoNormal">when i submit the AIMD task on the server, it died immediately. The cp2k.out presents that  "found an  unknown keyword N in section_ROOT_". I guess it might be something wrong with the pseupotential or basis-set of element N. But i did't
 find anything wrong.  And i also search the section_ROOT in the manual, i found no results. Have you ever met such problem?<u></u><u></u></p>
