External Email - Use Caution
Hi,
While running the recon_all, I bumped into this error message below and failed to create a brainmask. I could not attach the T1.mgz and log file because the file were too big.
When I looked through, the white matter intensity were only between 70-90. It is pretty much an entire white matter intensity that I think it may be difficult to manually add control points.
What would be your suggestions? I have added screenshots of the freeview.
