    <p>Hi Joey,</p>
    <p>You have special characters in your files which cp2k cannot
      handle: <br>
    </p>
    <p>tabs (\t) in cp2k.inc and carriage return (\r) in cp2k.inp</p>
    <p>if you are on linux you can do the following:</p>
    <p>sed -i.bak 's/\r//g;s/\t/ /g' cp2k.inp cp2k.inc</p>
    <p>which will remove these characters or convert them to spaces.
      This should solve your issue.<br>
    </p>
    <p>Cheers,</p>
    <p>Fabian<br>
