dear douglas
thanks for your answer. I understand the developer is not maintaining the program computing lGI. however, my question refers ultimately to the recon-all preprocessing. I am trying to make it run again using different random seed, but apparently it uses the same random seed. or am I wrong? whether this rerun with a new random seed solves the lGI problem is yet to be proven.
thanks
fabio

Sorry, the developer of this program has moved on in her career so we have no one to support it anymore. We maybe looking at it again in the next year or so.

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
