@Adam: Thanks :-D. Concerning your question: It is the top-left corner (this seems to be the standard for image-based data). You can change that only by exporting data from PIVlab and then writing a custom script (shouldn't be that difficult however).

@Petra: Yes that might work. But then you'll have to select the "A-B, B-C, ..." sequencing style, otherwise you might skip every 2nd image.

@Petra: Yes, just select your reference image as "image A" for image pair.

@Joe: What you see is the vector validation between the passes. This doesn't really affect your end result. All vectors of the final pass are "real vectors", they are not interpolated.

@Elizabeth: You need texture in the medium that you want to track. As a rule of thumb: If your eyes can see a movement in the images, then PIVlab will also be able to do a cross-correlation.

@Edouard: I did something similar in my PhD project, but you need to do the calculations in Matlab. I can recommend Paraview for displaying the 3D data.

Hi Roe,
to export the 2D vector data, go to file -> save -> ASCII File or MAT File or Paraview binary VTK (depending on the format you want it to have).
The documentation will be available this summer in my thesis and (hopefully) also in a journal...

PIVlab is by far and away the best PIV software that I've used, even better than proprietary stuff that wants lots of money for the "full" version!

I have a question: I'm trying to convert Cartesian coordinates to polar coordinates. Where does PIVlab place x=0 y=0? At the bottom left hand corner? Is it possible to change the default location of 0,0? (As this would make converting easier.)

I changed in the PIVlab_GUI.m in Line 1631 the "filepath{i}" to "filepath{1}".

I think this will do the trick.
