Using Workbench Command

CONVERT BINGHAM PARAMETER VOLUMES TO FIBER ORIENTATION FILE
   wb_command -convert-fiber-orientations
      <label-volume> - volume of cifti structure labels
      <fiber-out> - output - the output fiber orientation file

      [-fiber] - repeatable - specify the parameter volumes for a fiber
         <mean-f> - mean fiber strength
         <stdev-f> - standard deviation of fiber strength
         <theta> - theta angle
         <phi> - phi angle
         <psi> - psi angle
         <ka> - ka bingham parameter
         <kb> - kb bingham parameter

      Takes precomputed bingham parameters from volume files and converts them
      to the format workbench uses for display.  The <label-volume> argument
      must be a label volume, where the labels use these strings:
