   wb_command -label-mask
      <label> - the label file to mask
      <mask> - the mask metric
      <label-out> - output - the output label file

      [-column] - select a single column
         <column> - the column number or name

      By default, the output label is a copy of the input label, but with the
      'unused' label wherever the mask metric is zero or negative.  if -column
      is specified, the output contains only one column, the masked version of
      the specified input column.
