Good morning,

I used freesurfer (v.5.1.0) on one subject using the MRI data and I finished the recon-all step and qcache -all. I was able to display the thickness map but I would like to get a quatitative measure of cortical thickenss for my subject for the 34 neuroanatomical regions per hemisphere(4 medial temporal, 5 lateral temporal, 11 frontal, etc) and display this data in a table where I want to include the number of vertices and the cortical tickness for different regions:

caudalanteriorcingulate, caudalmiddlefrontal, cuneus entorhinal fusiform inferiorparietal inferiortemporal isthmuscingulate lateraloccipital lateralorbitofrontal lingual medialorbitofrontal middletemporal parahippocampal paracentral parsopercularis parsorbitalis parstriangularis pericalcarine postcentral posteriorcingulate precentral precuneus rostralanteriorcingulate rostralmiddlefrontal superiorfrontal superiorparietal superiortemporal supramarginal frontalpole temporalpole transversetemporal insula MiddleFrontal InferiorFrontal OrbitoFrontal FrontalLobe CingulateCortex MedialTemporal LateralTemporal Parietal Occipital Region R unknown bankssts caudalanteriorcingulate caudalmiddlefrontal cuneus entorhinal fusiform inferiorparietal inferiortemporal isthmuscingulate lateraloccipital lateralorbitofrontal lingual medialorbitofrontal middletemporal parahippocampal paracentral parsopercularis parsorbitalis parstriangularis pericalcarine postcentral posteriorcingulate precentral precuneus rostralanteriorcingulate rostralmiddlefrontal superiorfrontal superiorparietal superiortemporal supramarginal frontalpole temporalpole transversetemporal insula MiddleFrontal InferiorFrontal OrbitoFrontal FrontalLobe CingulateCortex MedialTemporal LateralTemporal Parietal Occipital

I believe the thickness data is stored in lh. thickness and I should be able to read it in matlab but I am not very shure how.

Also I want to estimate the cortical thickness for gyral based regions of interest ROIs. The gyral-based ROIs should be derived from an automated labeling system that subdivides the cerebral cortex on volumetric MRI into 34 neuroanatomical regions per hemisphere.

I don't know how to do this so would you advise/teach me please?

Many thanks for your valuable help! Antonella ------------------------------
