Thanks for the question Maris, I have been wondering the same.
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?

Dear Fieldtrip users,
Can someone please explain the reason why in the tutorial http://www.fieldtriptoolbox.org/tutorial/sourcemodel<redir.aspx?REF=LS5FarOkwP8TA2JeL7GD9rSHEi2JYy_dxSVgVGLmjLdHy0UjYmnTCAFodHRwOi8vd3d3LmZpZWxkdHJpcHRvb2xib3gub3JnL3R1dG9yaWFsL3NvdXJjZW1vZGVs> (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?
This is what I am refering to:
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...
