Visualization and Analysis of Gene Expression Data
P roducing microarray data starts with scanning in the glass, gel or plastic slides with a specialized scanner to obtain digital images of the results of an experiment after hybridization. With the help of image analysis software the DNA expression levels are then quantified. After the image processing and analysis step is completed we end up with a large number of quantified gene expression va...

Weber Lawrence Berkeley National Laboratory Bernd Hamann University of California, Davis Hans Hagen University of Kaiserslautern, Germany Summary Recent methods for extracting precise measurements of spatial gene expression patterns from threedimensional (3D) image data opens the way for new analysis o...
متن کاملGenome-Wide Pathway Analysis and Visualization Using Gene Expression Data
Visualization of results for high performance computing pose special problems due to the complexity and the volume of data these systems manipulate. We present an approach for visualization of c-DNA microarray gene expression data in metabolic and regulatory pathways using multi-resolution animation at different levels of detail. We describe three scoring functions to characterize pathways at t...
متن کاملInteractive Visualization and Analysis for Gene Expression Data
New technology such as DNA microarray can be used to produce the expression levels of thousands of genes simultaneously. The raw microarray data are images which can be transformed into gene expression matrices where usually the rows represent genes, the columns represent various samples, and the number in each cell characterizes the expression level of the particular gene in a particular sampl...
متن کاملVisualization of microarray gene expression data
Microarray gene expression data is used in various biological and medical investigations. Processing of gene expression data requires algorithms in data mining, process automation and knowledge discovery. Available data mining algorithms exploits various visualization techniques. Here, we describe the merits and demerits of various visualization parameters used in gene expression analysis.
