<p>Dear Yihong,</p>
<p>this error only exists in older simnibs versions prior to version
4. Please make sure you have the latest version installed, and
that the paths are set to the latest version. You can test by
opening a cmd or shell window and typing</p>
<p>charm</p>
<p>If that isn't found, please check your path settings. When you
have head models created with simnibs 3 which you want to go on
using, please use the command convert_3_to_4 before using these
headmodels in simnibs 4.<br>
</p>
<p>Best regards,</p>
<p>Axel</p>
