Some of the user-interface components provide tooltips including the
"Apply RGB paint L...". If you place the mouse over a control and do
not move the mouse for a few seconds a tooltip appears describing the
control. Look for the section titled "Surface Coloration Applies to
Group" in
"http://brainvis.wustl.edu/CaretHelpAccount/caret5_help/dialogs/display_control_dialog.html
" for more information about L-to-L R-to-R.

We report the coordinate at the center of the voxel. If the volume is
in MNI stereotaxic space, it is an MNI coordinate. If the volume is
in a Talairach space, it is a talairach coordinate. If you are
looking for the voxel indices that identify the slice indices, they
are integers listed as IJK.
