convert diffusion-weighted images to tensor images.
| -grad encoding | specify the diffusion-weighted gradient scheme used in the acquisition. The program will normally attempt to use the encoding stored in image header. 
| encoding | the gradient encoding, supplied as a 4xN text file with each line is in the format [ X Y Z b ], where [ X Y Z ] describe the direction of the applied gradient, and b gives the b-value in units (1000 s/mm^2). |  | 
| -ignoreslices slice volumes | ignore the image slices specified when computing the tensor. 
| slice | the z coordinate of the slice to be ignored |  | volumes | the volume numbers of the slice to be ignored |  | 
| -ignorevolumes volumes | ignore the image volumes specified when computing the tensor. 
| volumes | the volumes to be ignored |  | 
| -info | display information messages. | 
| -quiet | do not display information messages or progress status. | 
| -debug | display debugging messages. | 
| -help | display this information page and exit. | 
| -version | display version information and exit. |
