DO A VECTOR OPERATION ON CIFTI FILES
   wb_command -cifti-vector-operation
      <vectors-a> - first vector input file
      <vectors-b> - second vector input file
      <operation> - what vector operation to do
      <cifti-out> - output - the output file

      [-normalize-a] - normalize vectors of first input

      [-normalize-b] - normalize vectors of second input

      [-normalize-output] - normalize output vectors (not valid for dot
         product)

      [-magnitude] - output the magnitude of the result (not valid for dot
         product)

      Does a vector operation on two cifti files (that must have a multiple of
      3 columns).  Either of the inputs may have multiple vectors (more than 3
      columns), but not both (at least one must have exactly 3 columns).  The
      -magnitude and -normalize-output options may not be specified together,
      or with an operation that returns a scalar (dot product).  The
      <operation> parameter must be one of the following:

      DOT
      CROSS
      ADD
      SUBTRACT
