  • Patent number: 7031528
    Abstract: A scanner system analyses data plotted in a scatter plot in accordance with user-specified criteria or statistical measures from the data population, to produce a scatter plot that displays in the plotted data the boundaries for the selection of out-lyer points and/or otherwise visually denotes in the plotted data which points are the out-lyer points. The scanner system analyzes the underlying data based on user-specified differential expression ratios, or based on criteria associated with the statistics of the data population, to produce out-lyer boundaries that are represented by diverging lines. Alternatively, the system may analyze the underlying data based on absolute expression levels, to produce boundaries that are represented in the plot by lines that meet at an identity line of slope 1.

  • Patent number: 6754375
    Abstract: Method and system are disclosed for interactively developing at least one grid pattern, such as a microarray pattern, as well as an array set of such patterns, and a computer-readable storage medium having a program for executing the method given only a few user inputs through the use of a pointing device such as a mouse or trackball on a personal computer or workstation. Each array in the set typically has an identical number of rows and columns of points.

  • Patent number: 6362832
    Abstract: Method and system for overlaying at least three microarray images to obtain a multicolor composite image, which is then displayed on a monitor of a computer system. The microarray images are taken from a microarray scanner of a DNA microarray and can be viewed simultaneously through the use of the image overlays where each image is represented by a different color. Each pixel of the composite image is generated by the OR operator applied to all corresponding pixels of the microarray images. Registration of the microarray images can be altered with a keyboard or mouse of the computer system.
