Abstract
A DNA flow cell processing method including positioning the flow cell on a stage at a predetermined location relative to a camera, illuminating the flow cell from a side with a first light source to reflect light off the DNA fragment bead locations, obtaining a first image of the flow cell and identifying a first reference pattern of bead locations in the first image, moving at least one of the flow cell and the stage relative to the camera, attempting to reposition the stage at the predetermined location, obtaining a second image of the flow cell, identifying the first reference pattern in the second image, and evaluating a first offset, relative to the camera, between the first reference pattern in the first image and the first reference pattern in the second image.
