Gifti image shen 268


I am having trouble interpreting the surface rendering (gifti image) of 268 parcellation.

I realized it contains 219 unique values (ranging 1-265). I would expect it to have 269 unique IDs which is why I might be missing any relevant details.

In particular, the 219 values correspond to the files 395091.R.func.gii and 395091.L.func.gii altogether. I downloaded them from the following link: NeuroVault: Shen k=268 parcellation

Many thanks in advance!
