External Email - Use Caution

Dear FreeSurfer experts,

I try to explore the Gyrification Index of both hemispheres in a population. For this I computed the LGI using the Freesurfer pipeline and used the command suggested in previous mails:

mri_segstats --slabel subject lh $SUBJECTS_DIR/subject/label/lh.cortex--i

$SUBJECTS_DIR/my_subject_id/surf/lh.pial_lgi –excluded 0 --sum lh.aparc.pial_lgi.stats

Based on:(*MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be* https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg67629.html https://secure-web.cisco.com/1_9wsKWw32_G-UJUtVnh9GwxfZh3NF5eNv2TMJEx0j2bPyqs2NlaE8loxeu_G2qWqjmT4bO2EPMS4vISS9lZNIslcKm2Jdcqq0MoKDYu69HTM15pFPnB4TcTKfzNfB-xNJRBbYsoEVNrjGsK1HsBobD3b4PkwdY6QpMuF1NzZ5mMAAP30RD5JFM9DcfFI0ESOGR9PzJRF7BjCG4EJ-IiW_MzTuGElxcHbpnFN7TBzwlxeJTWCDS4nqUNjBGAbaS3Vlm8dFP5Qcdpr8eHxGL6tiGgn37biAsMPRs9KSVA1Y1bNWzwZ_HTSqm7ps_89W7SeWfJCSoLXtIGY7BMLk0D_yQ/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg67629.html)

With this I get one line of results for this hemisphere in this subject in the file lh.aparc.pial_lgi.stats

….

Thank you for your help and time. Kind regards, Céline Steger
