Thank you very much Bruce!
The only files that I have in stats directory after running recon-all and qcache -al are the following:
lh.aparc.a2009s.stats lh.entorhinal_exvivo.stats rh.curv.stats lh.aparc.stats rh.aparc.a2009s.stats rh.entorhinal_exvivo.stats lh.BA.stats rh.aparc.stats wmparc.stats
As you can see there is no aparc.annot.ctab file but if I open rh.aparc.stats and rh.aparc.a2009s.stats I can find some information about cortical thickness. Is this data OK to be used for my cortical thickness measurements?
Thank you very much! Antonella
Hi Antonella,
those regions should be compiled in the stats/aparc.annot.ctab file that should be easy to import into excel or other packages for analsys and plotting.
cheers Bruce

Good morning Bruce,
I posted my message also to the list and I will appreciate any help I can get ASAP.
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

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 in terest ROIs. The gyral-based ROIs should be derived from an automated labeling system tha t 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
