    out_list: (a list of items which are any value)
            List of output nifti files

## LookupMeta

Link to code

Lookup meta data values from a Nifti with embeded meta data.

### Example

    >>> from nipype.interfaces import dcmstack
    >>> lookup = dcmstack.LookupMeta()
    >>> lookup.inputs.in_file = 'functional.nii'
    >>> lookup.inputs.meta_keys = {'RepetitionTime' : 'TR',                                    'EchoTime' : 'TE'}
    >>> result = lookup.run()
    >>> result.outputs.TR
    9500.0
    >>> result.outputs.TE
    95.0

Inputs:

    [Mandatory]
    in_file: (an existing file name)

             keys which are any value and with values which are any value)
            List of meta data keys to lookup, or a dict where keys specify the
            meta data keys to lookup and the values specify the output names

Inputs:

    [Mandatory]

    [Optional]
    ignore_exception: (a boolean, nipype default value: False)
            Print an error message instead of throwing an exception in case the
            interface fails to run

Outputs:

    None

            filename(s)
    split_dim: (an integer)
            Dimension to split along. If not specified, the last dimension is
            used.
