Hello, I have a participant with an error in their white matter segmentation, and after troubleshooting, it still doesn’t look right. Hoping someone on here will let me know how to fix it.
Skull stripping left some dura on the superior part of the brain, and initially it was labeling the dura as white matter. I ran gcut, then manually edited the rest of the dura out. It was then labeling some of the gray matter as white matter, so I put in control points along the actual white matter in that area.
After my interventions, the segmentation is better but still looks funky. And when I run my mouse over the area incorrectly labeled as white matter, it shows a wm value of 0. So I’m not sure why it’s labeling it as white matter at all.
I’ve included pictures of an affected slice just after recon-all as well as after all the interventions (both with and without surfaces). I also included the inflated surface before and after.
Thank you, Hailey Mulder
