SNOMAD (Standardization and NOrmalization of MicroArray Data): web-accessible gene expression data analysis

SNOMAD (Standardization and NOrmalization of MicroArray Data): web-accessible gene expression data analysis

SNOMAD is a collection of algorithms for the normalization and standardization of gene expression datasets derived from diverse biological and technological sources. In addition to conventional transformations and visualization tools, SNOMAD includes two non-linear transformations which correct for bias and variance which are non-uniformly distributed across the range of microarray element sign...

cDNA Microarray Data Normalization

Normalization and Differential Gene Expression Analysis of Microarray Data

DNA microarray technologies have the capability of simultaneously measuring the abundance of thousands of mRNA-sequences. Analysis of microarray data involves many different steps such as image analysis, background correction, and normaliza-tion, but also more classical statistical analysis such as testing for significant differences between groups of arrays. The work presented in this thesis i...

Normalization methods for analysis of microarray gene-expression data.

This paper investigates subset normalization to adjust for location biases (e.g., splotches) combined with global normalization for intensity biases (e.g., saturation). A data set from a toxicogenomic experiment using the same control and the same treated sample hybridized to six different microarrays is used to contrast the different normalization methods. Simple t-tests were used to compare t...

Microarray Data Analysis Toolbox (MDAT): for normalization, adjustment and analysis of gene expression data

SUMMARY We introduce a novel Matlab toolbox for microarray data analysis. This toolbox uses normalization based upon a normally distributed background and differential gene expression based on five statistical measures. The objects in this toolbox are open source and can be implemented to suit your application. AVAILABILITY MDAT v1.0 is a Matlab toolbox and requires Matlab to run. MDAT is fre...
