摘要:
A method and system for quantifying and correcting spatial-intensity trends for each channel of a microarray data set having one or more channels. The method and system of one embodiment of the present invention selects a set of features from each channel of the microarray data set. Based on the selected set of features, a surface is used to determine the intensities for all features in each channel of the microarray data set. Spatial-intensity trends within the microarray data set are quantified, based on the surface to the intensities for each channel of the microarray data set. After the surface has been determined, the spatial-intensity trend can be removed from the microarray data set.

Methods, systems and computer readable media for automatically generating information from chemical arrays. A plurality of image files representative pf features contained on a plurality of substrates, respectively, may be automatically and sequentially generated. Automatic and sequential feature extraction of the image files may be carried out, wherein automatic feature extracting of a first of the automatically generated image files is begun immediately after completion of the generation of that image file while a next substrate is being processed for automatic generation of a next image file therefrom. Methods, systems and computer readable media are provided for automatically generating information from chemical arrays, to include identifying an entity selected from the group consisting of data structures, directories, subdirectories and drives into which image files created from reading the chemical arrays are to be stored; polling the entity for the presence of a next new image file not identified in a most recent previous polling of the entity; automatically feature extracting the next new image file; outputting results from the step of automatically feature extracting the next new image file; iterating the step of polling the entity until a next new image is identified or until a predetermined time or predetermined number of polls have been reached; and repeating the steps of automatically feature extracting, outputting results and iterating polling when a next new image file is identified prior to passage. of the predetermined time or completion of the predetermined number of polls with an iteration.

A system and method of operating a data processing system to provide feature extraction from an image obtained from a plurality of chemical arrays is disclosed. The method includes bifurcating processing of the image by performing image processing and post-processing. The image processing includes processing parts of the image, each part corresponding to a different one of the arrays, in an automated batch process, to produce image-processed outputs that are different from the image and contain information extracted from the image. The post-processing includes processing the image-processed outputs according to different post-processing protocols with respect to different ones of those parts of the image corresponding to at least two of the arrays, to produce post-processed outputs. The method includes outputting at least one of the image-processed outputs and/or at least one of the post-processed outputs.

Methods, systems and computer readable media for bifurcating automated feature extraction processing of chemical arrays. A plurality of arrays may be image-processed sequentially, and then, outputs resulting from the image processing of at least two of the plurality of the arrays may be post-processed in an automated batch process to obtain processed outputs. In another aspect, a plurality of arrays may be image-processed in an automated batch process, and then outputs resulting from the image processing may be post-processed according to different post-processing protocols with respect to at least two of the plurality of the arrays. In another aspect, an array may be image-processed, and then an output of the image processing may be post-processed in an automated batch process, where at least two different post-processing protocols are assigned to the output of image processing, so that processed outputs are outputted for each of the processing protocols. In still another aspect, methods, systems and computer readable media perform inter-array analysis. A first array is image-processed with a first image processing protocol to obtain a first output, a second array is image-processed with a second image processing protocol to obtain a second output, and the first and second outputs of the image processing of the first and second arrays are post-processed together in an automated batch process to obtain processed outputs. In another aspect, methods, systems and computer readable media are provided for feature extraction processing multiple arrays contained on a single substrate. The multiple arrays are image-processed in an automated batch process, and then outputs of individual arrays, resulting from-image processing of the multiple arrays, are post-processed according to at least one post-processing protocol.
摘要:
One disclosed embodiment is a method based on an iteratively employed Bayesian-probability-based pixel classification, used to refine an initial feature mask that specifies those pixels in a region of interest, including and surrounding a feature in the scanned image of a microarray, that together compose a pixel-based image of the feature within the region of interest. In a described embodiment, a feature mask is prepared using only the pixel-based intensity data for a region of interest, a putative position and size of the feature within the region of interest, and mathematical models of the probability distribution of background-pixel and feature-pixel signal noise and mathematical models of the probabilities of finding feature pixels and background pixels at various distances from the putative feature position. In a described embodiment, preparation of a feature mask allows a feature-extraction system to display feature sizes and locations to a user prior to undertaking the computationally intensive and time-consuming task of feature-signal extraction from the pixel-based intensity data obtained by scanning a microarray.
