Is there a way to generate an intersection between a cortical thickness stats map (e.g., sig.mgh) in fsaverage space and native space neuroanatomy using FS parcellations (e.g., lh.apac.anot.)?  We would like to plot cortical thickness of the significant clusters for each subject, but separate the significant clusters by the parcellations, e.g., if the significant cluster spans parahippocampal and fusiform cortex, I would like those plotted separately (preferably w/o drawing ROIs--and again, not using the entire PHC or fusiform parcellation--only the portion that is significant in the group analysis).
