Dear HCP users, HCP has released thickness, surface area values based on DK (Desikan-Killiany) atlas in a csv file. I would like to extract those values using Destrieux atlas. To verify, whether am I following the correct procedure, I have extracted regional cortical thickness data using MATLAB from the HCP directory (/HCP_1200/100206/MNINonLinear/Native/) using DK atlas and compared with HCP released values. The values are same. Now, I am using connectome-workbench to estimate regional surface area using DK atlas. However, the extracted value does not match with HCP provided value.
To extract the area of left bankssts area (key 1) from /HCP_1200/100206/MNINonLinear/Native/, I am using the following connectome workbench commands: wb_command -gifti-label-to-roi 100206.L.aparc.native.label.gii roi.func.gii -key 1 wb_command -metric-weighted-stats roi.func.gii -sum -area-surface 100206.L.midthickness.native.surf.gii -show-map-name Could you please tell me whether am I using the correct commands? When I used *pial*.surf.gii or *white*.surf.gii instead of *midthickness*.surf.gii file in the second command, still the extracted value does not match with the HCP released value. Once I figure out the correct approach, I would replace the *aparc.*.label.gii file in the first command, with *aparc.a2009s*.label.gii to extract surface area using Destrieux atlas.
