Hello,
I am using FS 5.1 to measure lGI (local Gyrification Index). Only one
particular scan failed. Here are some messages:
³... remeasuring lGI value for vertex iV = 65101. It may take a few minutes.
WARNING -- Problem for vertex iV = 65101, lGI value is aberrantly high
(lGI=56.5472)...
...lGI computation will be stopped. This may be caused by topological
defects, check mris_euler_number on the pial surface.²
³mris_euler_number ../surf/lh.orig \n
euler # = v-e+f = 2g-2: 143555 - 430659 + 287106 = 2 --> 0 holes
F =2V-4: 287106 = 287110-4 (0)
2E=3F: 861318 = 861318 (0)
total defect index = 0²
³mris_euler_number ./lh.pial-outer-smoothed
=================
euler # = v-e+f = 2g-2: 65560 - 196674 + 131116 = 2 --> 0 holes
F =2V-4: 131116 = 131120-4 (0)
2E=3F: 393348 = 393348 (0)
total defect index = 0²
I re-run the recon-all -s 01_097_Y0 -hemi lh -autorecon2 autorecon3
and recon-all -s 01_097_Y0 -localGI
It stopped at the same vertex.
Could you please let me know anything I can do to overcome this issue? Thank
you very much.
Wayne
