eddy(infile, mask, acq_file, index_file, bvecs, bvals, outfile = NULL,
  retimg = TRUE, opts = "", verbose = TRUE, ...)

`infile`	input filename of 4D image.
`mask`	Mask filename (or class nifti)
`acq_file`	A text-file describing the acquisition parameters for the different images in `infile` The format of this file is identical to that used by topup (though the parameter is called `--datain` there).
`index_file`	A text-file that determines the relationship between on the one hand the images in `infile` and on the other hand the acquisition parameters in `acq_file`.
`bvecs`	A text file with normalised vectors describing the direction of the diffusion weighting.
`bvals`	A text file with b-values describing the "amount of" diffusion weighting
`outfile`	Output file basename
`retimg`	(logical) return image of class nifti
`opts`	Additional options to pass to arguments passed to `eddy`
`verbose`	print diagnostic messages
