Hi Bruce, Thank you very much for your response. I have two problems in particular that I am trying to solve. In one subject, a sulcus did not initially get identified, and after the fixes, it was only partially identified. I uploaded example images to http://nmr.mgh.harvard.edu/~nbilenko/seg/subj1_sag140.tif and http://nmr.mgh.harvard.edu/~nbilenko/seg/subj1_sag140_fixed.tif What could be causing that?
In another subject, some white matter in the temporal lobe did not get identified, even after adding points to wm.mgz. Example images are in: http://nmr.mgh.harvard.edu/~nbilenko/seg/subj2_hor140.tif and http://nmr.mgh.harvard.edu/~nbilenko/seg/subj2_hor140_T1.tif I suspect that this might be due to signal dropout due to sinuses - is that likely to be the case? Is there any way to fix it?
