I realise that it's not the best setup but it's mostly for learning purposes and should suffice as is. The thing that still confuses me though is that the 10-20 template set does include fiducials whilst the M10 does not.</div><div class=""><br class=""></div><div class="">I've tried manual interactive alignment before but to no avail since the head model doesn't make it very easy to find landmarks. I've also encountered errors when attempting to perform non-linear transformations regardless of the cfg.warp setting.</div><div class=""><br class=""></div><div class="">Anyway, I've solved the issue by utilising a template MRI from SPM which used the MNI coordinate system as a basis for the head model and transformed electrode positions to MNI as well. It appears to be rather tidy so for now all is good.</div><div class=""><br class=""></div><div class="">Yours sincerely,</div><div class="">Milan</div><br class=""><div><blockquote type="cite" class=""><div class="">On 20.3.2015, at 10:29, Herring, J.D.
