Using Workbench Command

CREATE A CIFTI LABEL FILE
   wb_command -cifti-create-label
      <cifti-out> - output - the output cifti file

      [-volume] - volume component
         <label-volume> - label volume file containing the data to be copied
         <structure-label-volume> - label volume file that defines which voxels
            to use

      [-left-label] - label file for left surface
         <label> - the label file

         [-roi-left] - roi of vertices to use from left surface
            <roi-metric> - the ROI as a metric file

      [-right-label] - label for left surface
         <label> - the label file

         [-roi-right] - roi of vertices to use from right surface
            <roi-metric> - the ROI as a metric file

      [-cerebellum-label] - label for the cerebellum
         <label> - the label file

         [-roi-cerebellum] - roi of vertices to use from right surface
            <roi-metric> - the ROI as a metric file

      All input files must have the same number of columns/subvolumes.  Only
      the specified components will be in the output cifti.  At least one
      component must be specified.

      The -volume option requires two volume arguments, the label-volume
      argument contains all labels you want to display (e.g. nuclei of the
      thalamus), whereas the structure-label-volume argument contains all CIFTI
      voxel-based structures you want to include data within (e.g.
      THALAMUS_LEFT, THALAMUS_RIGHT, etc).  See -volume-label-import and
      -volume-help for format details of label volume files.  If you just want
      the labels in voxels to be the structure names, you may use the same file
      for both arguments.  The structure-label-volume must use some of the
      label names from this list, all other label names in the
      structure-label-volume will be ignored:
