Netview is a tool that allows to explore the co-expression network surrounding a gene of interest. The user can select one of the two species analyzed (i.e. human and mouse). The type of identifiers; probeset refers at the microarray model HG-U133A for human and Mouse430_2 for mouse species. If the user select a tissue, the visualization tool will provide a check-box to highlight those interactions that connect genes significantly expressed into the selected tissue.
