aparc parcellation can't find reference data

[soichih]

I've run this App (using v1.3 branch) and noticed that various reference data is missing from the graph

Inside the reference data repo. I see these JSON files

lh_G_and_S_paracentral.json
rh_G_and_S_paracentral.json
...

My guess is that, lh_paracentral can't match the lh_G_and_S_paracentral.json. I wonder if we should rename those .json files and remove "G_and_S" when it tries to look for the json file for parcellation that contains "G_and_S".. I am afraid there is structural difference between "lh_paracentral" and "lh_G_and_S_paracentral", however.. If that is the case, we will need to generate reference data using different parcellations?
