[Mne_analysis] vertices in STC and source files

[Daniel Wakeman]

Ricky,

There is a fixed amount because you always use the same settings when you
run mne_setup_source_space. There are many options in there to generate a
source space with in principle as many vertices you want up to the number of
vertices for a participant (the manual explains in much more detail).

This information exists in the forward matrix in the .nearest field of the
forward matrix structure (when using the matlab toolbox). Though usually,
labels are best generated in mne_analyze (the manual explains this in
detail) or through freesurfer.

Good Luck!
