Hello,
I have just edited 12 control points in the OFC/Gyrus rectus area of one of our subjects. I added 12 control points, all to regions of WM that were below 110 and I was very pleased with the output for that region once I ran -autorecon2-cp -autorecon3. However, this resulted in the temporal lobe on the same side to be almost completely neglected by the wm/pial surfaces. Areas that were originally considered WM (even though many areas were below 110 intensity) are now completely left out.
What could be the cause of this? Am I changing the intensity threshold globally by editing the control points in one region?
Thank you in advance,
Philip
Hi Philip,
it's hard to see without looking at the data. Can you send us the brain.mgz, wm.mgz, orig.mgz and the control point file (tmp/control.dat) to start with and we'll take a look? Bruce
