Hi all


I am running recon-all –localGI
One subjects image is not getting processed and crashes repeatedly with message that there may be a topological defect in a particular vertex. It asks me to check euler number.
The wiki indicates that this crash is a known issue and restrating _mris_compute_lgi must solve this.

My questions are
  1. how to check the euler number and how to interpret this number in terms of topological defects?
  2. mris_compute_lgi  does not find lh.pial surface when I TRY TO RESTART  - what should I do? I used mris_compute_lgi  subjid/surf/lh.pial

Many thanks in advance
Lena
