Once there is node correspondence between the ROI
dataset and the surface datasets, then you should be
able to use normal 3d* programs on them, such as
3dROIstats, which gives stats for one ROI at a time.
To get node correspondence, I believe there are 2
steps (I am not a master of this):
1. Convert the ROI to a niml dataset, e.g.
ROI2dataset -label_dset lh.NEW.niml.dset -input lh.DRAWN_ROI.niml.roi
2. Create a full dataset that has all nodes (not just
those in the ROI), e.g.
ConvertDset -i lh.NEW.niml.dset -o_NIML -pad_to_node ld120 -prefix FINAL
See the
suma.pdf class handout for details, along with
run_ROI2dataset and run_ROIdump in the
suma_demo/afni
class data directory.
