Hi, I'm trying to change my ROI volume data to surface dset. Is it correct to use 3dVol2Surf in this case? If so, should I put my volume ROI file as input for -grid_parent or -map_func (or -mask?)?

Eventually what I would like to do is to visualize only the boundaries (contours) of the ROIs on the surface..
