[Mne_analysis] Source localization - obj.orig.pnt missing

[Alexandre Gramfort]

hi Evelyn,

the cortical src space is defined with respect to freesurfer meshes (eg
white, pial or inflated)
and precise what vertices are "inuse" in the source space. To get a
standard mesh
you need to combine the src space with the white surface.

See:

http://martinos.org/mne/stable/auto_tutorials/plot_forward.html#compute-source-space

let me know if you have more questions.

Hope this helps

Alex
