Abstract
A method of analyzing reagent beads retained in a sample well of a sample plate is disclosed comprising obtaining an image of a reagent bead, distributing intensity values of image pixels amongst a plurality of intensity bins and generating an histogram. A curve is fitted to the histogram and the curve is compared with an idealized profile of image pixels. A closeness of fit between the curve and the idealized profile is determined and then intensity values are discarded from one or more of the intensity bins. The remaining intensity values are redistributed and the process is repeated several times. A determination is then made as to which curve has the closest fit with the idealized profile.
