[FieldTrip] Question on performing EEG source reconstruction to atlas cortical sheet

[Michael Houston]

Hi Tzvetan, thank you for such a swift response. I believe this
tutorial could be useful. The tutorial  states somewhere the following:

"We first load the precomputed mni-standard Desikan-Killiani atlas, BEM
headmodel and the sourcemodel."

Does this mean to say that all the example files for this tutorial
(headmodel/sourcemodel/atlas) all correspond to the standard MNI brain
template? If so, that would also be useful for my analysis. Can you please
confirm?

Thanks,
Michael
