	                   {1,2,3,-1,-2,-3} {1,2,3,-1,-2,-3} {1,2,3,-1,-2,-3}
	
	Flip (ex, x --> -x) or swap (ex, x <-> y) chosen axes of the gradient sampling
	matrix. Result will be saved in the same format as input gradient sampling
	file.
	
	positional arguments:
	  in_gradient_sampling_file
	                        Path to gradient sampling file. (.bvec or .b)
	  out_gradient_sampling_file
	                        Where to save the flipped gradient sampling file.Extension (.bvec or .b) must be the same as in_gradient_sampling_file
	  {1,2,3,-1,-2,-3}      The final order of the axes, compared to original order: x=1 y=2 z=3.
	                        Ex: to only flip y: 1 -2 3.
	                        Ex: to only swap x and y: 2 1 3.
	                        Ex: to first flip x, then permute all three axes:  3 -1 2.
	
	options:
	  -h, --help            show this help message and exit
	  -v [{DEBUG,INFO,WARNING,ERROR}]
	                        Produces verbose output depending on the provided level. 
	                        Default level is warning, default when using -v is info.
	  -f                    Force overwriting of the output files.
