    Abstract: A method for determining false positives calls in a biological data plot is provided. The method includes identifying a first data cluster as non-amplification data points within the biological data plot and identifying a second data cluster as wild-type positives within the biological data plot. The method further includes estimating a position in the biological data plot of a center of the first and second data clusters. The method further includes determining, for each data point within the first data cluster, a probability of belonging to the first data cluster and determining, for each data point within the second data cluster, a probability of belonging to the second data cluster. The method includes applying a probability threshold for each data point within the first and second data cluster to identify false positives.

    Abstract: A method for improving image quality is provided. The method includes receiving image data of a substrate, wherein the image data is generated by imaging the substrate, and an image is generated from the image data. The method further includes generating a background representation from a background noise portion of the image, wherein the background portion includes signal information undesired for further processing and generating a background subtracted image by subtracting the background representation from the image. In this way, a separate background image is not needed to subtract the background from the image including the regions-of-interest to improve image quality.
