Wraps command camino_to_trackvis

Wraps camino_to_trackvis from Camino-Trackvis

Convert files from camino .Bfloat format to trackvis .trk format.

### Example

    >>> import nipype.interfaces.camino2trackvis as cam2trk
    >>> c2t = cam2trk.Camino2Trackvis()
    >>> c2t.inputs.in_file = 'data.Bfloat'
    >>> c2t.inputs.out_file = 'streamlines.trk'
    >>> c2t.inputs.min_length = 30
    >>> c2t.inputs.data_dims = [128, 104, 64]
    >>> c2t.inputs.voxel_dims = [2.0, 2.0, 2.0]
    >>> c2t.inputs.voxel_order = 'LAS'
    >>> c2t.run()

Inputs:

    [Mandatory]
    data_dims: (a list of from 3 to 3 items which are an integer (int or
             long))
            Three comma-separated integers giving the number of voxels along
            each dimension of the source scans.
            flag: -d %s, position: 4
    in_file: (an existing file name)
            The input .Bfloat (camino) file.
            flag: -i %s, position: 1
    voxel_dims: (a list of from 3 to 3 items which are a float)
            Three comma-separated numbers giving the size of each voxel in mm.
            flag: -x %s, position: 5
    voxel_order: (a file name)
            Set the order in which various directions were stored. Specify with
            three letters consisting of one each from the pairs LR, AP, and SI.
            These stand for Left-Right, Anterior-Posterior, and Superior-
            Inferior. Whichever is specified in each position will be the
            direction of increasing order. Read coordinate system from a NIfTI
            file.
            flag: --voxel-order %s, position: 6

    [Optional]
    args: (a unicode string)
            Additional parameters to the command
            flag: %s
    environ: (a dictionary with keys which are a newbytes or None or a
             newstr or None and with values which are a newbytes or None or a
             newstr or None, 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
    min_length: (a float)
            The minimum length of tracts to output
            flag: -l %d, position: 3
    nifti_file: (an existing file name)
            Read coordinate system from a NIfTI file.
            flag: --nifti %s, position: 7
    out_file: (a file name)
            The filename to which to write the .trk (trackvis) file.
            flag: -o %s, position: 2
    terminal_output: (u'stream' or u'allatonce' or u'file' or u'none')
            Control terminal output: `stream` - displays to terminal immediately
            (default), `allatonce` - waits till command is finished to display
            output, `file` - writes output to file, `none` - output is ignored

Outputs:

    trackvis: (an existing file name)
            The filename to which to write the .trk (trackvis) file.

## Trackvis2Camino

Wraps command trackvis_to_camino

Inputs:

    [Mandatory]
    in_file: (an existing file name)
            The input .trk (trackvis) file.
            flag: -i %s, position: 1

    [Optional]
    append_file: (an existing file name)
            A file to which the append the .Bfloat data.
            flag: -a %s, position: 2
    args: (a unicode string)
            Additional parameters to the command
            flag: %s
    environ: (a dictionary with keys which are a newbytes or None or a
             newstr or None and with values which are a newbytes or None or a
             newstr or None, 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
    out_file: (a file name)
            The filename to which to write the .Bfloat (camino).
