Hi, I download the Freesurfer 4.0.3 and installed it on linux,I tested it on the subject bert which is included in /freesurfer/subjects, I run "recon-all -s bert -localGI"

but it exited with errors as follows: lGI for vertex number 20101 of the outer mesh is 3.0478 lGI for vertex number 20201 of the outer mesh is 3.0267 lGI for vertex number 20301 of the outer mesh is 2.4033 lGI for vertex number 20401 of the outer mesh is 3.2432 lGI for vertex number 20501 of the outer mesh is 1.7832 lGI for vertex number 20601 of the outer mesh is 2.5316 lGI for vertex number 20701 of the outer mesh is 2.4154 lGI for vertex number 20801 of the outer mesh is 3.2481 lGI for vertex number 20901 of the outer mesh is 1.2247 lGI for vertex number 21001 of the outer mesh is 2.7509 lGI for vertex number 21101 of the outer mesh is 1.9534 WARNING -- Problem for vertex iV = 21201, lGI value is aberrantly high (lGI=47.7803)... ...lGI computation will be stopped. This may be caused by topological defects, check mris_euler_number on the pial surface.
