Dear FreeSurfer experts, I am trying to find the surface ROIs for (volumetric) parcellation ROIs, as mentioned in: Frye, RE et al. 2010. Surface Area Accounts for the Relation of Gray Matter Volume to Reading-Related Skills and History of Dyslexia. Cerebral Cortex 20:2625-2635.
I have run all subjects through the recon-all stream, and now want to project the inferior frontal, fusiform, angular, and supramarginal gyri to the surfaces. I've been able to find these ROIs in: <subject>/label/aparc.annot.a2009s.ctab: 25 G_pariet_inf-Angular 20 60 220 0 and <subject>/label/aparc.annot.ctab 07 fusiform 180 220 140 0 31 supramarginal 80 160 20 0 18 parsopercularis 220 180 140 0 20 parstriangularis 220 60 20 0 For the above, I'm assuming this means that in the relevant volume files (aparc.a2009s.+aseg.mgz & aparc+aseg.mgz), the voxels with intensities as labelled correspond to to the gyri. How do I project these regions to the subject surfaces? I assume I must use 'mri_vol2surf', but there are so many options I'm not sure what to use. I'd very much appreciate some input!
