Thank you very much for the information. Yes. I checked the data and they look
exactly like what I want.
Thanks againLongchuan

Hi Longchuan,
Currently, I'm having file system issues accessing the HCP archives to check
this myself, but I suspect the HCP structural packages have files named like
*.atlasroi.*shape.gii. These are standard mesh ROI files that exclude the
medial wall and corpus callosum. I'm pretty sure there are pial surfaces in
the 32k and 164k directories, so you could use these standard atlasroi files
with those standard mesh pial surfaces.
I'm not sure if you are using HCP datasets, but if you are processing more than
one subject, there might be some value to using a standard ROI file for this
purpose.
