Dear all
as some other posted before me, sometimes the computation of lGI fails with the message (see for example: https://secure-web.cisco.com/1LP2MjWSbRkQqjVjAMGGAySVoeFkdNhk1cYwhbxxVDmXiHS..., https://secure-web.cisco.com/1SX9AQfa4jGFVZg4d2lSYl8OLuP3FfkC_3AnJY2mfKP8J9W..., https://secure-web.cisco.com/1SX9AQfa4jGFVZg4d2lSYl8OLuP3FfkC_3AnJY2mfKP8J9W...)
'lGI for vertex number 35901 of the outer mesh is 2.5958 ... remeasuring lGI value for vertex iV = 36001. It may take a few minutes. WARNING -- Problem for vertex iV = 36001, lGI value is aberrantly high (lGI=53.1127)... ...lGI computation will be stopped. This may be caused by topological defects, check mris_euler_number on the pial surface.'
as many reported before me, computation of euler number gives 2, i.e. nothing wrong. another suggestion by marie schaer is to rerun recon-all -hemi ?h -autorecon2 -autorecon3 , with or without the -randomness option.
The point is that the -randomness option seems to have no effect, the error occurs again in exactly the same place, with the exact same value (lGI=53.1127).
I am using freesurfer 7.1. Has there been any development to solve this?
Thank you in advance
