Hello freesurfer experts,

I have successfully finished running the recon-all analysis without any errors for a dataset scanned on the 1.5T GE scanner. The output GM/WM surfaces however look incorrect and I am not sure what may have gone wrong. See attached screenshot from tkmedit. Any suggestions how to fix this would be helpful.

I have processed other datasets collected from the same scanner using the same sequence which seem to have correctly identified the pial and grey-white boundaries. I am using freesurfer-Linux-centos4_x86_64-stable-pub-v4.3.1.

Thanks, Mayuresh
