Hi Freesurfer experts,
I am new to FreeSurfer and I have a question.
I
have markers of EEG electrodes on the T1 image of a subject and I want
to project them from the scalp to his pial surface (that I reconstructed
using the standard procedure).
To do so, I manually selected the central point of each marker in
tkmedit and I defined a control point. Then I red that control point
with tksurfer on the corresponding pial surface. This should be the
projection to the pial surface: is this procedure correct? If yes, in
which coordinate system is the projection made?
