GoMiner: (Zeeberg et al., Genome Biology, March 2003) For Tour of GoMiner: Advance using forward arrow
GoMiner: (Zeeberg et al., Genome Biology, March 2003) GoMiner is a tool for biological interpretation of 'omic' data – including data from gene expression microarrays. Omic experiments often generate lists of dozens or hundreds of genes that differ in expression between samples, raising the question, “What the h-ll does it all mean biologically?” To answer that question, GoMiner leverages the Gene Ontology (GO) to classify the genes into biologically coherent categories and assess those categories statistically. For biological interpretation of a microarray experiment, the user enters the list of genes on the array and has the option of flagging them as up-regulated, down-regulated, or neither with respect to some index standard.
This animation presents a tour of the highlights of GoMiner’s functionality and user interface. GoMiner: (Zeeberg et al., Genome Biology, March 2003)
