[Mne_analysis] visualizing "activation" regions with MNE

[Dan Wakeman]

Hi Mingbo,

This will depend on how the ROIs look from the criteria. You could try
to go through and generate a label using the vertex numbers you have
produced and tksurfer. i.e. select each of the vertices one by one and
use the draw line features to generate a closed ROI. This will likely
end up including more vertices than the ones, which have "passed the
criteria". It may also be influenced by the size of the source space
you use.
