Checkerboard Target Marker Location Failing

[bhodge24]

Hello,

I'm using a checkerboard target from Edmund Optics with a 50x50 grid of 1.4mm squares. My images and filenames seem fine, but the marker locations are failing. Is it because the checkerboard height and width aren't set correctly? The dropdown menu only goes up to 25 in length and width. I've included a screenshot of the calibration window.
