Hi Bruce,
I?ve attached a screen shot of a temporal pole of one of the brains that we have had issues with. Here the issue is that there is a lesion without a very clear boundary for the white matter and freesurfer was unresponsive to simply using white matter edits (placing 255s on the wm.mgz), and so we tried placing control points where we think the white matter boundary should lie. However, we know that control points should not be placed in these dark spots of a lesion.
Thank you,
Allison
