Data Analysis

One critical component of the DNA Array Core Facility is the expertise in the use of software tools for gene expression data/statistical analysis. The Core offers access to computer workstations and training and assistance in the use of several software packages specifically designed for analysis of microarray data. These include both commercial products (GeneSpring, Silicon Genetics; ImaGene, Biodiscovery; GCOS, Affymetrix) and publicly available softwares (BRB ArrayTools, NCI; SAM, Stanford; RMA, UC Berkeley; dChip, Harvard). These software products are used for image analysis, statistical testing, class prediction, clustering and estimation of expression levels from processed image files.
