Hi all,

I have just started using Paraview and so I apologize in advance for the question but I have not been able to find a solution.

I have a `vtk` file containing a set of points defined using `VTK_VERTEX`.  
The file also contains some data defined on each point.

This is the file:

```auto
# vtk DataFile Version 4.0
Unstructured Grid Example
ASCII
DATASET UNSTRUCTURED_GRID

POINTS 6 float
0 0 0
1 0 0
2 0 0
0 1 0
1 1 0
2 1 0

CELLS 6 12
1 0
1 1
1 2
1 3
1 4
1 5

CELL_TYPES 6
1

CELL_DATA 6
FIELD FieldData 2
firstData 1 6 float
1.0
2.0
2.0
3.0
1.0
3.0

secondData 3 6 int
1 2 0
1 3 0
0 2 0
0 0 0
4 1 0
3 0 0

```

I would like to move the position of the points according to `secondData` using the filter `warp by vector`.  
However, when I import the data, this filter is not available (I cannot select it).

What am I doing wrong?

Thanks in advance.

`WarpByVector` needs point array, ParaView doesnt know that you have only one point by cell, use `CellDataToPointData` first.
