    • A plurality of samples are tested for their ability to enhance or inhibit a biological process in a multiplexed diffusive assay. The assay is imaged after the biological process has produced spots in a medium that indicate the tested enhancing or inhibiting ability of the samples. The image containing the resulting spots are evaluated to determine which samples caused the spots to form. The location of spots are identified by user selection or through a gradient triangulation technique that determines spot locations by analyzing the slope of pixel intensities in numerous subimages. The spots may also be analyzed by parametrically modeling the spots and comparing the spot characteristics in the image to a spot function, to determine the location of hit spots in the image. The hit spot locations, corresponding to the location of tested samples in the assay that enhanced or inhibited the biological process, are output to facilitate further analysis of the test samples.
    • 测试多个样品在多重扩散测定中增强或抑制生物过程的能力。 在生物学过程在培养基中产生指示样品的增强或抑制能力的斑点之后,测定成像。 评估含有所得斑点的图像,以确定哪些样品导致斑点形成。 斑点的位置通过用户选择或通过梯度三角测量技术来识别,其通过分析许多子图像中像素强度的斜率来确定点位置。 也可以通过对斑点进行参数建模和将图像中的斑点特征与斑点函数进行比较来分析斑点,以确定图像中命中点的位置。 输出对应于增强或抑制生物过程的测定中测试样品的位置的命中点位置,以便于进一步分析测试样品。
