Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
APPLY WARPFIELD TO SURFACE FILE
   wb_command -surface-apply-warpfield
      <in-surf> - the surface to transform
      <warpfield> - the INVERSE warpfield
      <out-surf> - output - the output transformed surface
      [-fnirt] - MUST be used if using a fnirt warpfield
         <forward-warp> - the forward warpfield
      NOTE: warping a surface requires the INVERSE of the warpfield used to
      warp the volume it lines up with.  The header of the forward warp is
      needed by the -fnirt option in order to correctly interpret the
      displacements in the fnirt warpfield.
      If the -fnirt option is not present, the warpfield must be a nifti
      'world' warpfield, which can be obtained with the -convert-warpfield
      command.
