## P2PDistance

Link to code

Calculates a point-to-point (p2p) distance between two corresponding VTK-readable meshes or contours.

A point-to-point correspondence between nodes is required

### Example

    >>> import nipype.algorithms.mesh as mesh
    >>> dist = mesh.P2PDistance()
    >>> dist.inputs.surface1 = 'surf1.vtk'
    >>> dist.inputs.surface2 = 'surf2.vtk'
    >>> res = dist.run()

Inputs:

    [Mandatory]
    surface1: (an existing file name)
            Reference surface (vtk format) to which compute distance.
    surface2: (an existing file name)
            Test surface (vtk format) from which compute distance.

    [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
    weighting: ('none' or 'surface', nipype default value: none)
            "none": no weighting is performed, "surface": edge distance is
            weighted by the corresponding surface area

Outputs:

    distance: (a float)
            computed distance
