data extaction of boundary layer thickness

I would like to validate my results of flow over a flat plate with blasius solution.
I run the case in simplefoam and i could see my results in parafoam.
However i would like to compare the boundary layer thickness with blasius solution along the flat plate, but unsuccessful in extracting the data from the results i got.
I am trying to extract the data from parafoam is that possible, i also tried using sampledict file but it shows nothing.
How can i extract the data from the results i got.
Please help me with your suggestions.

A few suggestions:
1. Blasius' solution is for laminar flat plate flow, if you are using simpleFoam, which is a turbulent solver, make sure in the RASProperties file you have laminar selected as the "turbulence model" and turbulence turned off. I recommend using icoFOAM if you are solving a laminar problem.
2. In ParaFOAM you can get the data by using the filters>data analysis>plot over line. Once you have generated the graph then go to file> save data.
3. The sample file is probably empty because you are specifying data points outside your domain.
Hope this helps,
