  Where: 
  
     --returnparameterfile <std::string>
       Filename in which to write simple return parameters (int, float,
       int-vector, etc.) as opposed to bulk return parameters (image,
       geometry, transform, measurement, table).
  
     --processinformationaddress <std::string>
       Address of a structure to store process information (progress, abort,
       etc.). (value: 0)
  
     --xml
       Produce xml description of command line arguments (value: 0)
  
     --echo
       Echo the command line arguments (value: 0)
  
     --debug
       debug (value: 0)
  
     -p,  --progress
       show progress of processing (value: 0)
  
     --nolighting
       Set LightingOff. (value: 0)
  
     --nonormal
       Do not use vtkPolyDataNormals. (value: 0)
  
     --zoom <double>
       zoom factor. Used when visualzing the vtk file.
  
     --png <std::string>
       output png file. Used when visualzing the vtk file.
  
     --bg <std::vector<double>>
       background color for the window (value: 0,0,0)
  
     --angle <std::vector<double>>
       azimuth,elevation. Used when visualzing the vtk file. (value: 0.0,0.0)
  
     --size <std::vector<int>>
       window size. Used when visualzing the vtk file. (value: 600,600)
  
     --scale <double>
       Scale factor: length of the peaks. (value: 1000)
  
     --slice <std::vector<int>>
       coordinates for coronal, sagittal and transverse views. When -1 is
       used for x/y/z, then the voxel is visible in the x/y/z-axis. (value:
       -1,-1,-1)
  
     --box <std::vector<int>>
       only generate mesh from a given box (x0,x1,y0,y1,z0,z1). When -1 is
       used, then x0/y0/z0 will be 0, x1/y1/z1 will be the maximal number in
       the x/y/z-axis. (value: -1,-1,-1,-1,-1,-1)
  
     --flip <std::vector<int>>
       Flip x/y/z-axis for spherical functions. 1 means flip, 0 means
       no-flip. (value: 0,0,0)
  
     --scalarimage <std::string>
       Input file. (value: "")
  
     --scalarrange <std::vector<double>>
       Range of scalar used for coloring. If they are -1.0, then use minimal
       and maximal values. (value: -1.0,-1.0)
  
     --resolution <double>
       Glyph resolution. (value: 10)
  
     --colorscheme <FA|MD|IMAGE|DIRECTION|NONE>
       Color scheme. (value: DIRECTION)
  
     --glyph <LINE|ARROW|DISK|CYLINDER|CUBE|ELLIPSOID|SUPERQUADRIC>
       Glyph type/ (value: ELLIPSOID)
  
     -o <std::string>,  --output <std::string>
       Output vtk file. If it is not set, visualize the vtk file. (value: "")
  
     --,  --ignore_rest
       Ignores the rest of the labeled arguments following this flag.
  
     --version
       Displays version information and exits.
  
     -h,  --help
       Displays usage information and exits.
  
     <std::string>
       (required)  Input file. It is 1) an image file with tensors,        
       or 2) a .txt file with tensor elements (6 or 9 values) of a single
       tensor;         or 3) 6 or 9 float numbers as tensor elements.        
       If 6 elements, these 6 values should be [xx, xy, xz, yy, yz, zz]      
       If 9 elements, these 9 values should be [xx, xy, xz, yx, yy, yz, xz,
       yz, zz].
  
  
     Description: Create a mesh from tensors for visualization.
  
     Examples: 
  
     MeshFromPeaks tensors.nii.gz -o tensors_vis.vtk --scale 1000  
  
     MeshFromPeaks tensors.nii.gz  --scale 1000 --slice -1,-1,25
