Dear freesurfer experts After using the command of mri_glmfit-sim (mri_glmfit-sim --glmdir aaa.thickness(or thickness, volume, sulc, curv ).lh.10 --cache 1.3 pos --cwp 1 --2spaces). I check the data in the fie of cache.th13.pos.y.ocn.dat and found that the data of volume was so small ( e.g 1.39463 1.50616 2.53250).Data of thickness was same as volume (e.g 1.83629 3.01648 2.16078). Could you tell the unit of each index? And could the data be used as further analysis, e.g correlation with IQ or other behaviors?
Thank you

where are you getting those numbers? Thickness will be between 0 and 5, so those numbers look ok. doug
