External Email - Use Caution 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_3t4OH5UTR99dcG2qgX8efaQYfhcbbftI-T2HYptb4KL3ZxlJjmDP29gWStsqjsaXvuFBk4EbaR1a9qpkSEEv7T6728G9zmUkpM6YAnjA1vEPUDUxgGKRG01r5vncEqkblMdNFz83z_BWs17Fb8ykfKufUQ0xfAdSe0LltyVNpsoV8r0EqhFmBYnhc9cgJSDHJCTnacrHKTj903Cyhq_ipT6u0aXXfKPGPIywUCGjEtIJIpuB1YENqkI28eagbxGBMORYw7MZ-HDsYMxmE-9Hn6NPKsBI_SfwfFAoXqw/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg09284.html, https://secure-web.cisco.com/1SX9AQfa4jGFVZg4d2lSYl8OLuP3FfkC_3AnJY2mfKP8J9WeP4jQEkCEs7No1A_FAjMj-HuftunURSuN0N10wdCGoHGtBZGdUc3hRRmgwnciLVgKWNy5KLYZ3kxjxmP95hjyOoPZTfxxTflg0jrV1DDAI_8dvyMRdF4kPyU7DkdMg0Dszh18VasP42tZItX7TCxBzX98bzSpYlZwE5K_f0KVAMzrcgXoObWgHQ6AAzgmTxZ3iuxfkHadgKf1VMNkhheh6LWpdrPfewMYwN6ElTUiBM2Wd74K2w7Ni6J6qOIAA12IIN_nR_OXnKgZsh0MUN5b3RYmgVd6T3csf34S-Og/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg44781.html, https://secure-web.cisco.com/1SX9AQfa4jGFVZg4d2lSYl8OLuP3FfkC_3AnJY2mfKP8J9WeP4jQEkCEs7No1A_FAjMj-HuftunURSuN0N10wdCGoHGtBZGdUc3hRRmgwnciLVgKWNy5KLYZ3kxjxmP95hjyOoPZTfxxTflg0jrV1DDAI_8dvyMRdF4kPyU7DkdMg0Dszh18VasP42tZItX7TCxBzX98bzSpYlZwE5K_f0KVAMzrcgXoObWgHQ6AAzgmTxZ3iuxfkHadgKf1VMNkhheh6LWpdrPfewMYwN6ElTUiBM2Wd74K2w7Ni6J6qOIAA12IIN_nR_OXnKgZsh0MUN5b3RYmgVd6T3csf34S-Og/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg44781.html) '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 Fabio Bernardoni Dr. Fabio Bernardoni wiss.
