The MNE coreg crashes when I tried to load the raw data (.ds folder), I attached the errors by copy & paste from terminal after it crashing. I notice that, in both tutorials, the raw datas were ‘fif’ format, different with mine ‘.ds’, I am therefore wondering whether the problem was due to the file format or I did something wrong? Could you help how can I solve it?</div><div class=""><br class=""></div><div class="">Thanks </div><div class=""><br class=""></div><div class="">Bo </div><div class=""><a href="mailto:bo.zhang@pku.edu.cn" class="">bo.zhang@pku.edu.cn</a> </div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""></div></body></html>
