Consider this command: http://www.humanconnectome.org/software/workbench-command.php?function=-surface-closest-vertex
You can draw ROIs around the identified vertices on the surface with this command: http://www.humanconnectome.org/software/workbench-command.php?function=-surface-geodesic-rois You could then use -metric-reduce to make them into a single column, and then either use different palettes or palette settings on the right and left to color them differently, or turn them into label files to set their colors directly. Subcortical points are more difficult, but you can use the "volume" mode in wb_view to edit voxels in a new volume file. You can then use -volume-dilate to make them more sphere-like, then display them with the surfaces and metrics in "all" view, press the wrench icon for the volume, layer tab, "draw voxels as cubes (3D)" to see them all at once. There is also an older file format for foci, used in caret5, which is still supported for display, but we don't have many commands for that file type in workbench, so it may be more involved to get it to work. It displays the foci as spheres by default, so it would likely look better than the above method. I'm not sure how it deals with subcortical foci.
