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.
