Wraps command **dti_recon**

Use dti_recon to generate tensors and other maps

Inputs::

        [Mandatory]
        DWI: (an existing file name)
                Input diffusion volume
        bvals: (an existing file name)
                b values file
        bvecs: (an existing file name)
                b vectors file

        [Optional]
        args: (a string)
                Additional parameters to the command
        b0_threshold: (a float)
                program will use b0 image with the given threshold to mask out high
                        background of fa/adc maps. by default it will calculate threshold
                        automatically. but if it failed, you need to set it manually.
        environ: (a dictionary with keys which are a value of type 'str' and with values which
                 are a value of type 'str', nipype default value: {})
                Environment variables
        ignore_exception: (a boolean, nipype default value: False)
                Print an error message instead of throwing an exception in case the interface fails to
                run
        image_orientation_vectors: (a list of from 6 to 6 items which are a float)
                specify image orientation vectors. if just one argument given,
                        will treat it as filename and read the orientation vectors from
                        the file. if 6 arguments are given, will treat them as 6 float
                        numbers and construct the 1st and 2nd vector and calculate the 3rd
                        one automatically.
                        this information will be used to determine image orientation,
                        as well as to adjust gradient vectors with oblique angle when
        n_averages: (an integer)
                Number of averages
        oblique_correction: (a boolean)
                when oblique angle(s) applied, some SIEMENS dti protocols do not
                        adjust gradient accordingly, thus it requires adjustment for correct
                        diffusion tensor calculation
        out_prefix: (a string, nipype default value: dti)
                Output file prefix
        output_type: ('nii' or 'analyze' or 'ni1' or 'nii.gz', nipype default value: nii)
                output file type

Outputs::

        ADC: (an existing file name)
        B0: (an existing file name)
        FA: (an existing file name)
        FA_color: (an existing file name)
        L1: (an existing file name)
        L2: (an existing file name)
        L3: (an existing file name)
        V1: (an existing file name)
        V2: (an existing file name)
        V3: (an existing file name)
