<p class="MsoNormal">Hi <br>
I am trying to create a headmodel using template MRI and eeg recordings. Given is the piece of code that I have used. Issue is that in the final plot the headmodel and the sensor positions are not properly aligned. Can someone please tell me what part I am
missing here ? ‘ctf’ is the coordinate system of the sensors.<br>
Thanks<o:p></o:p></p>
