Thank you, Francois. Now, I understand, because here we use affine co-registration which is linear transformation, so the shape of the individual head in MNI space is still different from template.
The major part is the back side of head，it may be caused by the fiducial point does not cover information about this part.
Therefore, it still need to adjust electrode position manually.
So can nonlinear co-registration solve this problem here?(to avoid manual adjustment)
Best,
