ni vision assistant calibration

Hello to all.
I'm using Labview NI Vision Assistant to calibrate a square image (1024x1024) of a circular grid.
I use the command "Image Calibration" and I choose "Distortion Model" as the calibration type.
I do the steps, when I arrive at the "Step 6: Specify Axis Calibration" change the image size, but still the output calibrated image has size of 1024x1024.
Then I use the "Image Correction" command but the output image has different size from the original.
Can anyone tell me how can I solve this problem please?
I'd be grateful!
thank you!

Can you post your calibration grid so I can try the same steps?

I used Vision Assistant 2015 and got calibration sucessful following your steps. Not sure what is the issue.  Try to load the attached NIdotcalibration image and see what happens.

The NIdotCalibration.png image is the output of the calibration process.

ok, but I see that your output image and the original image are the same, it seems that your image is not calibrated. Sorry!
