This is a known issue when recon-all v8-beta is run a 2nd time. It will be fixed in the final v8 release. In the mean time, you can get around it with cd $SUBJECTS_DIR/subject/surf mris_compute_lgi --i lh.pial mris_compute_lgi --i rh.pial

Dear FreeSurfer Developers,

I'm attempting to compute the local gyrification index but unfortunately the calculations terminated with an error:

recon-all -subject XXX -localGI -hemi rh

FreeSurfer version: freesurfer-linux-ubuntu22_x86_64-8.0.0-beta-20241102-b8aacdc

The data was preprocessed before with recon-all and completed without any error and I've run this on multiple individuals without any success. The same commands worked fine with former FreeSurfer versions (6.0 and 7.3.2).

On the freesurfer mailing list I haven't detected this problem. I would be very greatful, if you have any idea how to run it in this new freesurfer version.

Best regards, Katharina
