Gabriel,

?h.pial_lgi is a curv file format similar to the ?h.thickness file, meaning that there is one value per vertex. So you can export the lGI values for all the vertices included in a ROI exactly as you would do it for cortical thickness.

However, I am not able to help you with your other question about white matter volume in ROIs.
