Hi Thang,
The Caudate and the Putamen are labeled. They should be in your aseg.stats file as "Left-Putamen" "Right-Putamen" "Left-Caudate" and "Right-Caudate". If they are not there then there is likely something wrong with your aseg.
the label that is specifically called "Left-Caudate/Putamen" and "Right-Caudate/Putamen" is not something that corresponds to a label in our aseg, and there are no plans to change the current labels.
You should be using the values from "Left-Putamen" "Right-Putamen" "Left-Caudate" and "Right-Caudate".
