Detects outliers in a functional imaging series

Uses intensity and motion parameters to infer outliers. If `use_norm` is
True, it computes the movement of the center of each face a cuboid centered
around the head and returns the maximal movement across the centers.


Examples
~~~~~~~~

>>> ad = ArtifactDetect()
>>> ad.inputs.realigned_files = 'functional.nii'
>>> ad.inputs.realignment_parameters = 'functional.par'
>>> ad.inputs.parameter_source = 'FSL'
>>> ad.inputs.norm_threshold = 1
>>> ad.inputs.use_differences = [True, False]
>>> ad.inputs.zintensity_threshold = 3
>>> ad.run() # doctest: +SKIP

StimulusCorrelation
-------------------

`Link to code <file:///build/buildd/nipype-0.9.2/nipype/algorithms/rapidart.py#L560>`__

Determines if stimuli are correlated with motion or intensity
parameters.

Currently this class supports an SPM generated design matrix and requires
intensity parameters. This implies that one must run
:ref:`ArtifactDetect <nipype.algorithms.rapidart.ArtifactDetect>`
and :ref:`Level1Design <nipype.interfaces.spm.model.Level1Design>` prior to running this or
provide an SPM.mat file and intensity parameters through some other means.

>>> sc.inputs.realignment_parameters = 'functional.par'
