Dear FS experts

I'm trying to calculate the local GI of my subjects but I'm having trouble with one of them, When I run recon-all -s MySubject -localGI it always give me the same message:


... remeasuring lGI value for vertex iV = 57301. It may take a few minutes.
WARNING -- Problem for vertex iV = 57301, lGI value is aberrantly high (lGI=47.3485)...
...lGI computation will be stopped. This may be caused by topological defects, check mris_euler_number on the pial surface.

ERROR: compute_lgi did not create output file '/root/trabajo/freesurfer/subjects/c_36/surf/tmp-mris_compute_lgi-lh.pial/lh.pial_lgi.asc'!

recon-all -s c_36 exited with ERRORS at Fri Oct 19 09:22:54 CEST 2012



When I checked the mris_euler_number on the pial surface I get no topological defect:

[root@localhost surf]$ mris_euler_number lh.pial
euler # = v-e+f = 2g-2: 134601 - 403797 + 269198 = 2 --> 0 holes
      F =2V-4:          269198 = 269202-4 (0)
      2E=3F:            807594 = 807594 (0)
total defect index = 0


Also try as: mris_compute_lgi --i lh.pial --echo
And get the following message:

... remeasuring lGI value for vertex iV = 57301. It may take a few minutes.
WARNING -- Problem for vertex iV = 57301, lGI value is aberrantly high (lGI=47.3485)...

The right hemisphere works perfectly...with this last command, but left just does not work.
Any ideas about this? any way to fix it??? Can anyone help me?
