<div>Dear all,</div>
<div><br>
</div>
Thanks for the question Maris, I have been wondering the same.
<div><br>
</div>
<div>Along those lines, I was wondering if it is appropriate to scale the resulting beamformer grids to match the size of the MNI template after the fact?
<div><br>
</div>
<div>thanks,</div>

<div>Dear Fieldtrip users,</div>
<div><br>
</div>
<div>Can someone please explain the reason why in the tutorial <a href="redir.aspx?REF=LS5FarOkwP8TA2JeL7GD9rSHEi2JYy_dxSVgVGLmjLdHy0UjYmnTCAFodHRwOi8vd3d3LmZpZWxkdHJpcHRvb2xib3gub3JnL3R1dG9yaWFsL3NvdXJjZW1vZGVs" target="_blank">http://www.fieldtriptoolbox.org/tutorial/sourcemodel</a>
(or in general, for that matter) the outer layer of grid points of the source model lie outside the brain though they are defined as being inside?</div>
<div><br>
</div>
<div>This is what I am refering to:</div>
<div><a href="redir.aspx?REF=J-IFW_IErPmt-H_p_1iAMMmBolt7L30eL_pBM_V-01ZHy0UjYmnTCAFodHRwOi8vd3d3LmZpZWxkdHJpcHRvb2xib3gub3JnL19kZXRhaWwvZXhhbXBsZS9tbmlzcGFjZS9tbmlfZmlnMWEucG5nP2lkPXR1dG9yaWFsJTNBc291cmNlbW9kZWw." target="_blank">http://www.fieldtriptoolbox.org/_detail/example/mnispace/mni_fig1a.png?id=tutorial%3Asourcemodel</a>

</div>
</div>
<div><br>
</div>
<div>According to my naive understanding, this means that in this model the potential neural sources may also lie outside the brain, which makes no sense. Clearly, I am missing something here...</div>
<div><br>
</div>
<div>Thanks!<br>
