Re: [Freesurfer] Mean lGI value extraction

Sorry Prapti, I was confused, the exact commands are: mris_anatomical_stats -a aparc.annot -t pial_lgi -f #SUBJ/stats/ lh.aparc_lgi.stats #SUBJ lh and then aparcstats2table --subjects #SUBJ1 #SUBJ2 ... --hemi lh --meas thickness --parc aparc_lgi --t YOUR_OUTPUT_TABLE Hope it will work, Ma

Do you mean you want abs(subj1-matched1)? There's no parametric way to test a hypothesis based on this, but if you want it you can run mri_concat --abs paireddiff.mgh abspaireddiff.mgh doug Mayuresh wrote: > Hi Doug, Nick and other freesurfer users, > > I have two groups and each group has a

Hi Prapti, Normally you can use aparcstats2table exactly as you would do with thickness, given that the column corresponding to thickness values in the tablefile that you produced with your mris_anatomical_stats are indeed lgi values (i.e. you used mris_anatomical_stats -t pial_lgi -f lh.l
