Hi Olga,
<div><br>
</div>
<div>The ‘template grid’ refers to a so-called source model, i.e. the set of positions that you use to model your sources.</div>
<div>The headmodel refers to the volume conduction model of the head.</div>
<div><br>
</div>
<div>The inverse warping is intended to facilitate group comparisons after the source reconstruction.</div>
<div><br>
</div>
<div>For the source reconstruction you can use these ‘inverse warped template grids’, but it is advisable to always use a volume conduction model based on the participant’s anatomy, as Simon already suggested in his reply.</div>
<div><br>

I believe it "align/project" the template grid with individual mri using non-linear transformation.<br>

Correct me if I'm wrong.<br>
I'll be more than happy to get more comments on this.<br>

<div>I would use the individual head model based on the MRI as it provides more information for your source analysis. This should provide more accurate results.</div>

<div>I think with this configuration the source model that is prepared is only based on the cfg.grid.template, and completely ignores the MRI (which you are interested in). This might explain why you see no difference.</div>
