<div>Hi Pramod,</div>
<div><br>
</div>
<div>I had similar problem for my MEG data because we did not collect the individual MRI data.</div>
<div><br>
</div>
<div>For source analysis in FieldTrip without individual MRIs, I used a simple sphere fitting and scaling method to fit a template (Colin 27, included in FieldTrip) to the polhemus headshape. First, a single sphere was fitted to the MRI scalp and another sphere
was fitted to the polhemus headshape. Then I scale the MRI sphere to the same size as the polhemus headshape sphere. And use the scaled MRI template for later source analysis in FieldTrip.</div>
<div><br>
</div>
<div>Some details, I usually remove the polhemus head points on the nose, also the lower part of the scalp (from MRI template).</div>
<div><br>
</div>
<div>Best,</div>
<div>Weiyong</div>
<p></p>
