ExpressionView
ExpressionView is an R package that provides an interactive environment to explore biclusters identified in gene expression data. A sophisticated ordering algorithm is used to present the biclusters in a visually appealing layout. From this overview, the user can select individual biclusters and access all the biologically relevant data associated with it. The package is aimed to facilitate the collaboration between bioinformaticians and life scientists who are not familiar with the R language.
Launch and download

Download the stand-alone viewer (adobe AIR)
If you prefer a stand-alone viewer, you can download and install the Adobe AIR build ExpressionView.air (right-click to download file).
To run the program, you need the AIR runtime environment which you can get from Adobe.
ExpressionView creates files associations to .evf files, allowing you to simply double-click on such files to launch the viewer and load the data.
